Musnad Ahmad #1020

It was narrated that ‘Ali (رضي الله عنه) said: When Abu Talib died, I came to the Prophet (ﷺ) and said: Your paternal uncle, the old man, has died. He said: “Go and bury him, then do not do anything about his affairs until you come to me.” So I went and buried him, then I came to him and he said: `Go and do ghusl, then do not do anything until you come to me.” So I did ghusl, then I came to him and he offered du`a` for me, and I would not be happy if I had red and black camels instead of that. Ibn Bakkar said in his Hadeeth: as-Suddi said: And ‘Ali (رضي الله عنه) used to do ghusl when he had washed a deceased person.
