They say in our doctrine that the word “God” is way different than “Allah”, and shouldn’t be said as long as the Kuffar use it. We as Muslims differ from what they came with.. Similar to what happened when Adan was first confirmed. What’s your take on that?
The Saudi scholar Ibn Uthaymeen says there is no issue with using foreign words to refer to God if the meaning of the word is commonly known and well-understood and not confusable with pagan deities.
I try to use the word “God” wherever I can if I am speaking or writing in English, because it sounds more natural than using “Allah”. My wife is a native English speaker and we always say “God” when we speak.
I come from a Kurdish culture and we always use Khwa and Khoda when we speak about God. It sounds highly unusual if someone says Allah in the wrong context, it is like saying “thou” and “thee” in English to refer to someone.
You will find some Arab-centric opinions on the internet that say to use “Allah” instead of other words, acting as if the cultural choices of hundreds of millions of non-Arab Muslims around the world are of no importance.
Using the word God in English is recommendable because it shows non-Muslim English speakers that we are not speaking of some foreign deity like some of them mistakenly think. It shows that we are speaking of the same God that they know of, the God of Abraham and Jesus, peace be upon them.For similar reasons I recommend that converts to Islam keep their pre-Islam names. A convert to Islam named Christopher is going to have a far easier time befriending and approaching non-Muslims, putting them at their ease and showing them that Muslims are just like themselves. If he chooses some foreign-sounding name, this will always act as a barrier.
Ultimately it comes down to personal choice whether a convert chooses to change their name or not. But it is a big mistake to tell them this should be one of the first things they should do after converting. This should be one of the last things they do, by choosing a foreign name they separate themselves from their local community and make it far more difficult on themselves to get their conversion to Islam accepted by others on the one hand, and to get others to have a friendly view of Islam on the other.
Additionally, converts to Islam who have children have the right to continue using local names, as long as these names do not have a meaning conflicting with Islam. Irish Muslims can continue using common Irish names, the way that Kurdish Muslims use Kurdish names, and Turkish Muslims use Turkish names.
