It is narrated from Hazrat Khuzaymah bin Thabit (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Sometimes Satan comes to a person and asks him, "Who created the heavens?" He replies, "Allah did." Satan asks, "Who created the earth?" He says, "Allah did," until Satan finally asks, "Then who created Allah?" When any of you experiences this condition, he should say: "I believe in Allah and His Messenger ( صلی اللہ علیہ وسلم )."
