Below are my preliminary thoughts on why Islam’s tolerance for slavery is not necessary unethical.

It may sound like nothing but empty apologetics to defend Islam’s toleration of slavery and say that Islam’s goal was to abolish it, when Islam’s Prophet ﷺ and his companions all practiced it widely. And generally this is what much of the arguments defending Islam’s views on slavery sound like when they come from traditional scholars.

It is difficult to reconcile classical Islam with modern views on slavery because classical Islam calls for applying the Quran and the Sunnah (the Prophet’s traditions ﷺ as recorded in hadith collections) as equal authorities. Since the Prophet ﷺ practiced slavery, the implication is that anyone can practice it without it being an issue. Saying slavery is morally wrong today is like saying the Prophet ﷺ did something morally wrong, which naturally is considered unacceptable. The Saudi Salafi scholar Saleh al-Fawzan, reflecting this kind of thinking, recently issued a fatwa (ruling) saying that terrorist groups operating in Iraq have the right to enslave women belonging to the non-Muslim Yazidi minority.

According to Abul A’la Maududi, the Prophet ﷺ freed 63 slaves by himself during his life. In his commentary on Ibn Hajar al-Asqalani’s Bulugh al-Maram, the historian Muhammad bin Isma`eel al-San`ani says that the Prophet ﷺ and his companions together freed over thirty-nine thousand slaves in their lives.

I will focus on early Islamic history, since what Muslims did after that did not always reflect Islamic principles. If we find moral justification for the Prophet’s practices ﷺ, then this is sufficient. It is not necessary to find moral justification for Ottoman practices regarding slavery, since what they did regarding slavery and a thousand other things does not necessary reflect the teachings of Islam.

Islam’s critics may say that we modern Muslims are trying to back-rationalize Islam’s “savage” beginnings by reinterpreting the Prophet’s actions ﷺ as if he wasn’t a vicious and power-seeking warlord. But as will be shown below, his policies and reforms regarding slavery were so noble and ahead of their time that he puts the Christians of a thousand years later to shame.

The Arabian System of Slavery

Slavery has been a part of life in most human societies. American Christians were having sexual intercourse with their black slaves by the tens of thousands only to refuse to take care of the children born in this way and deny them their right to a family. Since Christianity has no framework for dealing with slavery, the slaves and the children born would be abandoned, rather than taken care of as Islam would require.

At Islam’s beginnings, it was common practice to take the defeated enemy’s women as slaves, this was done by the pagans too. It was an ordinary and accepted part of life. Before Islam, Arabs had twenty ways of acquiring slaves according to the scholar Muhammad Mutawalli Sha`rawi, such as people being made slaves due to debt, or a tribe offering one of their own as a slave as an offering to another tribe, or one tribe attacking another with the purpose of enslaving them. Islam reduces these ways to only one way: Enemy prisoners coming out of a just war, not an offensive war done for gain, but a war done against an aggressor.¹ And if there are international treaties for dealing with prisoners of war, like there are today, then this way too would be closed.

So within the Islamic system, this is how slaves are created:

1. During an age of the world where slavery is a worldwide practice, some group launches a war of aggression against Muslims. The Quran expects Muslims to sign treaties with their neighbors and commands them to not be aggressors, therefore a war would only be against an enemy that has broken treaties. Of course, many Muslim states throughout history have abused Islamic law to justify wars of aggression, but the actions of Muslims are one thing, and Islamic principles are another. You cannot hold Islam responsible when Muslims break its laws. All major religions, ideologies and constitutions have been used to justify wars of aggression.
2. The enemy is offered peace but refuses to back down.
3. The enemy is conquered.
4. The enemy’s men, women and children are taken as captives and have the status of slaves, with a long list of rights ensured by Islam. Note that the enemy would have done the same to the Muslims if they had been the conquerors.

This is what happened to the Jewish Banu Qurayza tribe, who at Islam’s darkest hour, when the Muslims were under attack by a large alliance of pagan Arabs during the Battle of the Trench, broke their treaty with the Muslims and plotted with the attackers to help them destroy the Muslim state. Their men were executed for high treason (treason during a time of war, it is also the law in the United States to execute those convicted of high treason), and their women and children were enslaved. Executing the enemy’s men was done for their treason, this wasn’t the standard Islamic practice against enemies. And it wasn’t the Prophet’s judgment. The Jews demanded that their judge should be a Muslim man from Medina that they liked and trusted, and the Prophet agreed to delegate the judgment to that man. And that was his judgment.

In Islam’s early history, this enslavement of an enemy was not done out of aggression. An enemy, instead, initiated the aggression, with full knowledge of its potential consequences. In the case of Banu Qurayza, it was a risk they took, hoping to annihilate the Muslims on the one hand, and to take over their wealth, lands, women and children on the other. The risk they took did not pay off. Had they been successful, it would have been the Muslims who would have suffered execution and enslavement under the hands of the pagan Arabs and their Jewish accomplices.

Couldn’t God have asked the Muslims to do something morally superior to enslaving the women and children? He could have, but He didn’t.

The main reason for tolerating slavery could be that slavery took care of providing for the women and children acquired through war. The Jewish solution to this problem in Biblical times was to also kill the women and children, as is recorded in the First Book of Samuel in the Bible and in other places:

…and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass. (Samuel I, 15:3)

Christians did the same at times, for example:

Albert of Aachen, a chronicler of the First Crusade era, explicitly claims that the Arab soldiers capture and enslave virgins. (According to him, the Christians just kill everyone.)

[From a historian’s answer posted on Reddit]

Muslims, being more civilized, did not kill people needlessly, and especially not women and children. The killing of women and children in war is strictly prohibited by Islamic law.

New populations of slaves acquired during war would be mostly women and children (because the men were mostly dead, since the wars in those times were often “total wars”, where all the males fought). If this population of mostly women and children had been abandoned, they could have starved, since they had no men to take care of providing for it.

The Prophet ﷺ couldn’t have asked the Muslims to take care of these women and children without getting anything in return. Food, clothing and houses did not magically fall from the sky; it required much labor to provide these. Politically it could have been highly damaging to his cause to force the men to become practically slaves of the interests of this defeated population, building them new neighborhoods of homes in their towns and feeding and clothing them without getting anything in return. Doing this would have also led to a great increase in prostitution and theft, because this new population of women and children would have had no alternative ways for advancing in life. This is what happened in New York City in the 1850’s when a great number of unmarried Irish women and children were dumped into the city, escaping famine in Ireland. Their neighborhoods turned into ghettos full of crime, as happens to all jobless and idle populations, and the meme that Irish Americans are dirty criminals lasted for over a century afterwards.

The Prophet ﷺ could have asked his followers to marry these women and take care of their children. This wouldn’t have worked because only a man who had two homes and the income to maintain both could have married a second woman. They couldn’t keep two wives under the same roof, because this is practically guaranteed to cause marital discontent (it is quite difficult enough for a man to manage two wives living under separate roofs). Most men did not have a second home or the income to maintain one. So marrying these women wouldn’t have been practical, a few of the women could been married, but not most.

As a reminder, I am describing the reasons why Islam tolerated slavery in the ancient world. As I will describe below, Islam today does not tolerate slavery and Muslims around the world have supported banning it, this is not because Islamic principles have been abandoned for modern principles, it is because the Quran supports us in doing what we know to be the just and kind thing, while also tolerating slavery in societies that already practice it. The Quran has an anti-slavery agenda, but its agenda requires that it should tolerate slavery if a society already practices it, ending it from the inside. Societies that already practice slavery may be violently opposed to the thought of abandoning slavery, as the example of the American Civil War shows. Islam’s toleration for slavery enables it to spread in such societies and gently reform them until it can put an end to slavery.

So marriage was not a practical option. What was needed was a form of marriage that did not strongly compete with the man’s existing marriage, that did not require a second home, and that did not require high income for a man to engage in it. The Arabian system of slavery provided all of these features by enabling the women to work as servants in the men’s homes, in this way not being competitors in status to their wives. By giving the men the right to have sex with their female slaves, it made the men willing to keep them as slaves, otherwise they wouldn’t have wanted them (as will be described further).

In this way the women were taken care of and fed as were their children, they were not killed like Jews and Christians would have done, and they were not left to starve. These women grew up thinking of slavery and concubinage as a normal part of life and probably had them in their own homes, they saw nothing wrong with this as long as it was not happening to them. For them the difference between being a wife and a concubine was a difference in status, not a difference between a consensual sexual relationship and rape. This is evident to someone studying China and Japan’s ancient practice of concubinage. Concubines were neither wives nor mere sex toys. They had a specific social status, it was lower than that of a wife, but it is a highly naive view of history to think of such women as merely bodies that were abused and raped.

The Christians of Egypt gifted the Prophet ﷺ a Christian concubine named Maria. Were the Christians merely sending the Prophet ﷺ a sex toy as a gesture of good will? Of course not. As any historian of ancient times will tell you, this was similar to a man offering his daughter’s hand in marriage to someone else as the Christian Byzantine emperor Michael VIII Palaiologos did when he offered his daughter’s hand in marriage first to Hulagu then to Hulago’s enemies in his attempts to ally himself with the winning side. In such a marriage her own opinion in the matter was ignored, as has been standard practice among large sections of society in all of history, especially among the aristocracy. A concubine did not have to be placed in chains and shipped off in a box. For her this was her status in life, and she had no problem with doing it, similar to the way today female actresses do not mind having a male actor’s sexual organ inside them for a movie sex scene, it is part of their job and they do it.

The difference is that, in theory, concubinage was “forced”, while a modern actress is not “forced” to do that. But it all depends on the woman’s mindset. A concubine did not feel raped the way a modern woman forced into slavery would feel, she felt that she belonged to a lower-class caste of women, one of whose jobs was to have sex with their masters. She may have hoped for a better life, to one day be a full wife and not merely a concubine, but she had a respected social status and function, she thought of herself as an integral part of society, not as someone imprisoned and raped against her will like modern-day sex slaves are. These things do not justify slavery, but provide part of the explanation for why Islam tolerated it. A modern woman may value her own dignity so much that she may consider murdering anyone who tries to enslave her, but at that time, the women thought of concubinage as a forced, low-status marriage that would be their fate if their men failed to protect them, and they perfectly approved of it as long as it was happening to their sisters.

In the modern world, a sex slave is an unperson; she is a non-human commodity used and discarded as an animal. In Islam’s system, a concubine was a person. She had rights, she could own property, her master could be punished for mistreating her and he did not have the right to sell her if he got her pregnant. A sex slave has no place in society, her status is lower than even a family’s dog, because a family dog fits within the family and is loved and is respected. It has a place. A sex slave has no place. She has been dehumanized into an object whose opinions, rights and free will no longer exist. It is as if she is dead and animated by some form of magic that keeps her flesh alive so that she can continue performing her sexual functions. This is a far cry from concubinage in Islam, in which, first and foremost, the concubine has a place in society. She is not an unperson, she continues to be treated like a human. A low class of human, certainly, but still a human; people would treat her the way they treat the extremely poor among them.

In Hegelian terms, the sexual relationship between a master and his concubine is a relationship between subjects, while the relationship between a kidnapper and his sex slave in the modern world is a relationship between a subject and an object. For more on the important differences between subject-subject and subject-object sexual relationships please see Sexual Desire by the British philosopher Sir Roger Scruton.

In Islam, the relationship between a slave woman and her master is an official relationship, it is similar to a marriage. She cannot be in a sexual relationship with anyone else during this relationship (there are many stories of masters who would unscrupulously exploit their concubines and share them with other men, but that behavior is against Islamic teachings.). If she is already pregnant when acquired, her master does not have the right of having sex with her until she gives birth. If she becomes pregnant by her master, her master no longer has the right to sell her, because she acquires that status of umm walad and cannot be sold as a slave, becoming a semi-wife instead. Her children that are born to her and her master will be free citizens and not slaves, and if her master dies, she becomes a free woman herself. If Islam was a barbaric religion that taught its adherents to enslave people, why would it have so many sophisticated mechanisms for eradicating it?

What is the point of preventing a master from selling his slave once she is pregnant or has given birth? The Christian slave owners of America didn’t think there was any point in this, since they were not civilized enough to worry about the status and rights of the slave, while the Muslims of 630 AD found a point in this, because it enabled the woman to care for her children under the care and protection of her master, while also forcing the master to take full responsibility for the children, who were now free citizens. Americans just 160 years ago were savages in their dealing with slaves compared to the Arabs of 630 AD.

A person who has a limited view of history may think that the best solution to slavery is to ban it and let whatever happens happen afterwards, and this was the idea of the North in mid-19th century America, which led to the American Civil War², causing the death of about a million people (it was the bloodiest war in history up to that time). Since Islam was not invented by short-sighted humans, it respects the existing culture, enables an extremely undeveloped society to take care of the women and children who are victims of war (instead of killing them, allowing them to starve or encouraging them to become prostitutes and criminals by dumping them into cities), and provides various methods for slowly but surely eradicating slavery until it can be banned without any social unrest, the way almost all Muslim-majority countries today have banned slavery. Muslim Tunisia banned slavery before the United States did.

While these facts are, of course, not sufficient to justify slavery in the modern world, in the ancient world, given the political and economic circumstances of those times, it is understandable why Islam tolerated slavery.

It would be untrue to say that the Prophet tolerated slavery entirely out of charitable motivations. The Arabian system of enslaving war captives and distributing them was done as part of the distribution of war booty, the goods taken from a defeated prisoner. From Tariq Ramadan’s In the Footsteps of the Prophet:

Seven days had elapsed since the surrender, and the Hawazin had not appeared to ask for their womcn and children back. Now thinking that they would not come, Muhammad decided to share out the captives between the Quraysh Muslims (who once again received a more important share) and the Ansar. He only just finished the distribution when a Hawazin delegation arrived. The Prophet explained to them that he had waited for them, but since they had not arrived he had already shared out the captives; he said that he would intercede for them and ask people to give back their prisoners if they wanted to. After some hesitation, all the fighters gave up their captives to the Hawazin delegation. (Pages 184 and 185)

The Muslim fighters wanted the captives as their slaves. The Prophet, however, wanted them to wait for the captives’ tribe to come and hopefully sign a peace treaty, after which they would be given back to the tribe. Since the Hawazin didn’t seem willing to come for a treaty, the Prophet assumed they still intended war, and for this reason allowed the Arabian system to take its course, giving his warriors what they were used to get.

But once the Hawazin finally appeared, the Prophet showed his noble character and the non-Arabian-ness of Islam by convincing his fighters to give the captives back. Instead of acting like an Arab warlord, rejoicing in defeating and enslaving an enemy that had gathered to destroy the Muslims, he let them go free once their representatives came to ask for peace.

This scene also illustrates the sensitivity of the Prophet’s political situation. He could not force his fighters to give up the captives. They were from different Arabian tribes with their own ideas about their rights and their status in relation to the Prophet. The Prophet was not in charge of a “horde” of mindless soldiers like so many detractors of Islam wish to portray, he had to keep a sensitive political situation balanced, giving sufficient satisfaction to each section of his following so that they would not rebel against him.

He did not act like the largely Bolsheviks of Russia (led by the Jewish Vladimir Lenin), enforcing a new ideology on the entire population and giving everyone the option of either accepting it or dying. He humored the population, their pride, their culture and their various forms of social organization. He did not want to destroy society then rebuild it (like all Marxist and neo-Marxist ideologues wish to do), he peacefully gave his message to his society, giving them the option of either accepting it or leaving it, and never responding to the violence offered him and his followers. Only when he was elected the sovereign ruler of Medina by its main tribes did he start to act like a ruler, doing what was necessary to protect his state against aggressors.

And even then, he continued to respect the existing society and culture. Instead of acting like Lenin or Ayatollah Khomeini, using assassinations and purges to enslave the population to his interests in the name of the greater good, even though he was a prophet of God and had His authority behind him. He continued to respect them, consult them, while the Muslims continued to maintain the right to question and criticize his decisions. Even at the end of his life, when he had become the supreme ruler of Arabia, his companions severely criticized him to his own face after he chose a 17-year-old as the leader of a Muslim army. Instead of thinking “God’s messenger says so, therefore no argument can be admitted”, they treated him like a human and felt free to disagree with him, so that he had to convince them of the sense and rationality of his decisions.

In his truly democratic form of governance, in allowing everyone to voice their opinions and take part in decision-making, treating him like any other human, rather than as a supreme leader, he was a far cry from the typical modern dictator who expects absolute obedience, or the typical modern democratic leader who considers democracy an annoying formality that gets in the way of their achieving their goals, paying lip service to it while betraying its principles on a daily basis. It is all the more strange that someone who had over 100,000 people under him, considering him truly a messenger from God, would never make use of his status as God’s messenger to get his way, instead allowing people to challenge him daily.

Compare him to Ayatollah Khomeini, who by the virtue of (supposedly) belonging to the Prophet’s descendants and being the main religious authority of his sect, while in his weakness he professed to believing in democracy and spoke with non-Shia leaders like Ahmad Moftizadeh, once he achieved supremacy in Iran, he quickly went on to purge the government of his opposition, rushed the constitution he liked through the judiciary to the dismay of his opposition and his own friends, and used theological arguments to prove that his decisions could not be questioned.

The Prophet’s Concubines ﷺ

A person may acknowledge that politically and economically, it made some sense for Islam to tolerate slavery instead of banning it immediately. They may even acknowledge the fact that Islam in the modern world does not command slavery nor support it, since the Quran does not command the practice of slavery, and since we in the modern world dislike slavery and consider it repulsive, Islam gives us full rights to ban it.

But they may wonder why the Prophet ﷺ himself accepted to have slave women he had sex with (concubines). Couldn’t he himself, and his closest companions, have chosen the moral high ground of avoiding it?

We cannot find a conclusive answer for this, but we can speculate. Perhaps in God’s view, there was no good to be gained by prohibiting the Prophet ﷺ and his companions from keeping concubines when everyone else did. These women would have had masters anyway, so it wouldn’t have improved the lot of these women to prevent some Muslims from keeping them, it may have even worsened their lot, because many Muslims may have tried to follow the Prophet’s example ﷺ of not keeping concubines, creating large populations of female slaves that nobody wanted. And if the Prophet ﷺ had kept concubines without having sex with them, in this way practicing slavery without the sexual intercourse part, other Muslims may have tried to follow his example, and by so doing, they may have avoided keeping female slaves at all, since an important reason, perhaps 90% of the reason, for their wanting to take care of these slave women was that they received the privilege of intimacy with them. So the result, again, could have been large populations of female slaves that no one wanted. The result would have been that the slaves would have been sold to non-Muslims (since Muslims didn’t want them), and this wouldn’t have been better for the women, but worse, since the non-Muslims may have had no laws for protecting the rights of these slaves or providing them with ways for themselves or their children to be freed. So there would have been no moral gain from these choices.

By keeping concubines the way the rest of the culture did, the Prophet ﷺ showed the rest of the Muslims that they too could do this. In this way the society of that time was able to absorb conquered populations and slowly free them.

In Islam, slaves also have the right of mukataba, which was for them to be given free time in which to work, so that they could buy themselves off of their masters. In this way many male slaves were able to buy their own freedom. America’s slave owners of 1850 CE and their official laws considered their slaves and everything the slave owned as properties of their masters. Imagine their infuriation if they were told their slaves should be allowed to have free time in which to work, or that what they earned was not a property of the master, but a property of the slave. They, including their religious clergy, would have considered this a dangerous attack against their God-given rights over their slaves.

The Prophet ﷺ himself could have kept no concubines, saying that God had commanded him not to keep any, while making it lawful for everyone else. This could have affected his status negatively in the eyes of his followers and allies, since the concubines belonging to a man’s household added to his prestige. The Prophet himself ﷺ was part of Arabian culture, considering slavery and concubines a normal part of life, like everyone else did. God could have taught him that one day humans will discover that it is morally wrong to enslave people, but He did not for His own reasons, perhaps it served the interests of everyone, including the slaves, for the Arabian system to continue functioning like usual, with a few crucial reforms added to it to significantly reduce the number of new slaves, and to provide various ways for slaves to be freed.

While today we can think of various things the Prophet ﷺ could have done at that time instead of practicing slavery and concubinage, we can never be sure that our solutions wouldn’t fail miserably in that ancient Arabian context. We can never be sure if Islam’s solution wasn’t the best possible solution for that time and place, enabling a society to slowly eradicate slavery without causing civil wars, and without the religion being abandoned for being too ahead of its time if it had outright banned slavery.

Therefore a fair-minded reading of the Quran and early Islamic history will see that there is not sufficient justification for calling Islam a false or unjust religion for tolerating slavery at that time. They will see that the Prophet ﷺ was already greatly ahead of his time and that he made some incredible reforms in various areas of life, including reforms regarding slavery. Therefore the only thing they can criticize him for is not being even more ahead of his time, which is a pretty weak criticism. Who is to say that he wasn’t already operating as much ahead of his time as it was possible to be without people abandoning his movement?

Is Islam Outdated?

A person could say that now that the world is sufficiently developed, Islam is an outdated religion, that since it contains many rules and regulations regarding slavery, the religion must have been meant for ancient times and not today.

The truth is that there is no guarantee that the world will continue to be developed. Perhaps a nuclear war will break out 10,000 years from now and there will be isolated areas of the world that would live in conditions as basic as those of 630 AD, and in that case, there may again be warring entities that practice slavery, and Islam’s rulings regarding it would become relevant again.

Or humans could establish a colony on another planet where slavery is practiced. If some people among them convert to Islam while belonging to that culture that practices it, then Islam’s rulings regarding slavery would be relevant again.

Islam’s Historical Mistakes

It is true that various Islamic empires have acted aggressively and have sought to enslave not as a matter of practical necessity but for profit and pleasure. One could say that if Islam had forbad slavery, all of those evils would have been prevented. There is no way to know this for sure, because as explained, banning slavery may have been politically and economically unfeasible, and even if it had been banned, Muslims were still free to do a thousand other evil things.

Therefore a fair-minded person will not criticize the deeds of Muslims, but the program they follow. Islam is the program, and its programming logic makes Muslims avoid and ban slavery, therefore there is nothing to criticize today’s Islam for regarding slavery. You can, however, make this criticism:

I dislike the fact that in some isolated space colony 1000 years from now if slavery is already practiced, and if some people embrace Islam, I dislike that they will not ban it immediately but instead take a generation or two doing it.

A final question could be; why believe in a religion that has parts which require so much justification, why not just abandon it and embrace the modern world instead? Because Islam has undeniable soft evidence of its truth in the Quran, therefore the issue of slavery is a very minor thing for someone who has accepted Islam based on this evidence. In my essay God, Evolution and Abiogenesis: The Topological Theory for the Origin of Life and Species, I discuss the reasons why I believe in Islam.

Conclusion

The best of Christians have also acted as the best of Muslims in fighting slavery, therefore what I mentioned above is about Christian history, not Christian ideals. Christians continue to use Islamic history against Islam, so there is no injustice in doing the same towards Christian history, so that it is known that Christian criticism of Islam is generally quite ignorant of the ugly sides of Christian history. As for Christian work against slavery, from Wikipedia:

Several early figures, while not openly advocating abolition, did make sacrifices to emancipate or free slaves seeing liberation of slaves as a worthy goal. These include Saint Patrick (415-493), Acacius of Amida (400-425), and Ambrose (337 – 397 AD). Gregory of Nyssa (c. 335-394) went even further and stated opposition to all slavery as a practice. Later Saint Eligius (588-650) used his vast wealth to purchase British and Saxon slaves in groups of 50 and 100 in order to set them free.

Today, if there is a war of conquest between a Muslim nation and a non-Muslim one, then there would be no question of slavery, the enemy’s women would be treated according to modern practices. Muslim states officially recognize and respect international treaties, and the majority of Muslims have no problems with this. It is only barbaric, CIA-trained-and-funded groups like ISIS and al-Nusra which want to bring back slavery.

So it is true that Islam does not forbid slavery, and it is against the Quran and the Sunnah to say that the religion forbids it. But it does not encourage it either. It has a sophisticated approach toward it that takes the facts on the ground into account, regulating it and ending it when the time is right, rather than doing it too soon when it might cause starvation or war.

The fact that a child born to a female slave and her master is considered a free citizen, and the fact that the Quran strongly encourages the freeing of slaves is sufficient evidence for the fact that Islam came to end slavery, not to encourage it. If the Muslims before us made the mistake of encouraging slavery at times instead of fighting against it, we the Muslims of today are not required to act like them, and in fact are fully justified in disavowing their actions as we follow the Islamic program in the modern world.
