Anas bin Malik reported,

The Prophet ﷺ was with one of his wives when a man passed by. He called the man over, and when he came, the Prophet ﷺ said, "So-and-so, this is my wife so-and-so."The man replied, "Messenger of Allah, whoever I might have suspected, I would never have suspected you."The Messenger of Allah ﷺ said, "Satan flows through a person like the flowing of blood."
