Safiyyah bint Huyai (may Allah be pleased with her) reported: The Prophet (may Allah's peace and blessings be upon him) was once observing I‘tikāf, so I went to visit him at night. We talked for a while then I got up to leave. He got up with me to escort me - her dwelling was in the house of Usāmah ibn Zayd. Two men from the Ansār passed by. When they saw the Messenger of Allah (may Allah's peace and blessings be upon him) they quickened their pace, so he said to them: "Slow down. This is Safiyyah bint Huyai (my wife)." They said: "Subhān Allah! O Messenger of Allah," meaning: You are far above any suspicion. He said: "The devil circulates in the son of Adam like blood. I feared lest he should cast evil thoughts in your hearts (or he said: would cast something in your hearts)." Another narration reads: "Safiyyah came to visit him while he was observing I‘tikāf in the mosque during the last ten nights of Ramadan. So she stayed to talk to him for some time then got up to leave. The Prophet (may Allah's peace and blessings be upon him) got up to escort her until she reached the door of the mosque near Umm Salāmah's door..." Then the rest of the narration was reported with the same meaning.
