Safiyyah bint Huyai (May Allah be pleased with her), the Mother of the Believers, said: I came to visit the Prophet ﷺ while he was in the state of I'tikaf (seclusion) in the mosque during the last ten days of Ramadan. After having talked to him, I got up to return. The Prophet ﷺ also got up with me and accompanied me a part of the way. At that moment two Ansari man passed by. When they saw him they quickened their pace. The Prophet ﷺ said to them, "Do not hurry. She is Safiyyah, daughter of Huyai, my wife". They said: "Subhan Allah (Allah is free from imperfection)! O Messenger of Allah! (You are far away from any suspicion)". The Messenger of Allah ﷺ said, "Satan circulates in a person like blood (in the blood streams). I apprehended lest Satan should drop some evil thoughts in your minds". Al-Bukhari and Muslim.
