Hadith 4:831
Yazid ibn Harun narrated to us, he said: Sufyan ibn Husayn narrated to us, from al-Zuhri, from Urwah, from Aisha, she said: When the Messenger of Allah (peace and blessings of Allah be upon him) was in I'tikaf, he would not enter the house except for a need. She said: And I would wash his head while there was between me and him the threshold of the door.
