The Messenger of Allah (ﷺ) used to observe I'tikaf in the mosque and put his head near me through the opening of the apartment, and I would wash his head. Musaddad said: "And I would comb it while I was menstruating."
Sunan Abi Dawud Book 14, Hadith 157
← Previous Hadith And Yunus also narrated in a similar way from al-Zuhri, and no one supported Malik in his narration from 'Urwah from 'Umrah ; and Ma'mar, Ziyad b. Sad and others have also narrated it from al-Zuhri from 'Urwah on the authority of 'Aishah.

Sunan Abi Dawud Book 14, Hadith 156 Next Hadith → When the Messenger of Allah (ﷺ) was observing I'tikaf (in the mosque), I would come to him to visit him. I had a talk with him and then stood up. I then returned and he (the Prophet) also stood up to accompany me (to my house). Her dwelling place was in the house of Usamah b. Zaid. Two men from the Ansar (helpers) passed (by him at the moment). When they saw the Prophet (ﷺ), they walked quickly. The Prophet (ﷺ) said: Be at ease, she is Safiyyah daughter of Huyayy. They said: Be glory to Allah, Messenger of Allah! He said: Satan runs in man like blood. I feared he might inspire something in your mind, or he said: evil (the narrator doubted).
