Silsilah as-Sahihah 25 — Who created Allah? The answer

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Satan comes to you and says: Who created you? He says: Allah Almighty did. Then he will say again: So who created Allah Almighty? If such a doubt arises, then recite this supplication: «آمنت بالله ورسوله» 'I believe in Allah and His Messengers.' This action will remove that doubt."
