Hmam bin Yahya bin Dinar همام بن يحيى بن دينار · Funerals (Kitab Al-Jana'iz)

(Wash her) seven times or more if you think fit.

We went out with the Messenger of Allah (ﷺ) to the funeral of a man of the Ansar, but when we reached the grave, the niche in the side had not yet been made, so the Prophet (ﷺ) sat down facing the qiblah, and we sat down along with him.
