Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: Satan comes to one of you and raises questions in your heart, first asking, "Who created such and such? Who created such and such?" until he finally says, "Who created your Lord?" When anyone experiences such a whisper, he should seek refuge with Allah and abandon that satanic thought.
