It is narrated from Hazrat Anas bin Malik (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 that man by his name and said, "O so-and-so! This is my wife." The man said, "O Messenger of Allah (peace and blessings be upon him)! I could never think such a thing about you, though I might think it about anyone else." The Prophet (peace and blessings be upon him) said, "Satan flows through a person like blood."
