“Take it easy, she is Safiyyah bint Huyai.” They said: “Glorious is Allah, O Messenger of Allah!” And they were very upset by that (i.e., that he thought they may have some doubts). The Messenger of Allah (ﷺ) said: “The Satan flows through the son of Adam like blood, and I was afraid that he might cast some doubt into your hearts.”
Sunan Ibn Majah Book 7, Hadith 142
