In the Name of Allah, the Most Gracious, the Most Merciful
Who Created Allah?
Question: If everything needs a creator, then who created Allah?
Answer: This is just rhetoric and playing with words. In all practicality this scenario doesn't exist, and here's why:
Assumption: Every thing is created by "A"
Question: Who created "A"?
Answer: "B" created "A"
Question: Who created "B"?
Answer: "C" created "B"
Question: Who created "C"?
Answer: "D" created "C"
And so on and so forth.
You can keep asking this question until we exhaust the chain of creation. Ultimately, we will all have to agree one of 2 things: Either the "creator" is a product of random chance and accident, or some "thing" outside the realm of natural creation exists who is self-existing and doesn't need a creator.
Furthermore, things like "created" and "born" and "died" are physical things which require time and space. If there is an existence which is self-existing, then that means time doesn't affect Him because He doesn't get old, or get born, or dies. If time doesn't affect Him then that means He is outside the realm of time and space. If He is outside the realm of time and space then He lived before everyone else and will live after everyone else.
To understand this better, draw a straight line with blue ink on a piece of paper. Let this blue ink represent time. We know time exists so some "thing" has to initiate this line. So now you would draw a bracket in red ink at the begining of the line. As soon as we draw this bracket in red ink outside the line of time, we right away admit that this "thing" is BEFORE time starts. With time begins all other creation, and this "time" seperates the creation from the Ultimate Creator. Since this Ultimate Creator existed before the measurement of time began, for all factual and empirical purposes that makes Him, quite literally, "Eternal and Absolute."
Say: He is Allah, the One and Only; Allah, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him.
