I'm now making slowly process to turn to Islam (as a Muslim) after years of no Iman. However sometimes I can come across really blogs here that post Islamic posts that are really strict and even dark in someway. I feel like I can't keep it up if Islam requires me to hate other religions and groups so I end up not performing my prayers etc. because I don't feel peaceful at my heart. It feels as if I've come to the wrong religion.
Generally whenever you stray away from the Quran and put your focus on anything else, you will lose your understanding of God and get an inaccurate and even depressing view of Him and His religion. This is true even if you read books by inspiring writers like Ibn al-Qayyim, who focus too much on certain of God’s characteristics and less on others. Only the Quran is perfectly balanced, all other sources will contain some imbalance that can upset or mislead you.
It is the Quran that defines your mission in life, your principles, your philosophy, your ideals. When people say something that goes against anything in the Quran, reject it and go on with your life.
There is no such thing as an “Islam” that is independent of the Quran. Islam is nothing more or less than the Quran applied to the real world. Read the Quran and you will see that it will not tell you to hate other religions. Read In the Footsteps of the Prophet by Tariq Ramadan and you will see that the Prophet, , was an example of love and tolerance toward non-Muslims.
You should not allow others to define Islam for you. Do your own reading and learning, and if anyone says something that insults your intelligence or goes against your sense of justice, research it and ask others about it, and you will find out that there is always a sensible answer. Instead of giving in to others when they present a version of Islam that you find unacceptable, find your own tolerant and beautiful version of Islam and use it to challenge theirs.
Many of the “strict” Muslims you see are Salafis who believe that the best way to please God is to follow the authority of hadith as an equal to the Quran, while the school of Islamic thought that I follow is Quran-focused Islam, which considers the Quran the center of Islam. These two different approaches lead to very different types of Islam. Salafism is “strict” and thinks virtue is in strictness, which often leads to an intolerant and judgmental form of Islam, while Quran-focused Islam is tolerant and respects your dignity and individuality.
