It is narrated from Hazrat Anas (may Allah be pleased with him) that a man passed by the Prophet (peace and blessings be upon him) while one of his noble wives was with him. The Prophet (peace and blessings be upon him) called her by name so that the man would understand that she was the Prophet’s wife. The man said, "O Messenger of Allah (peace and blessings be upon him)! I could never think such a thing about you, even though I might think it about someone else." The Prophet (peace and blessings be upon him) said, "Satan flows through a person like blood."
