Does Satan's whisper by asking, "Who created God?" affect a person?

This obsessive whisper (waswas) does not affect you. The Prophet, peace and blessings be upon him, informed us that Satan comes to a person and asks him: "Who created such-and-such? ... Who created Allah?" The cure for this is to seek refuge with Allah from the accursed Satan and to stop thinking about it. So, if it crosses your mind, say: "I seek refuge with Allah from the accursed Satan," and cease it completely, turning away from it entirely, and it will disappear, by Allah's will.
