CHAPTER: How Many People Should Enter The Grave?
Narrated Amir: Ali, Fadl and Usamah ibn Zayd washed the Messenger of Allah صلی اللہ علیہ وسلم and they put him in his grave. Marhab or Ibn Abu Marhab told me that they also made Abdur Rahman ibn Awf join them. When Ali became free, he said: The People of the man serve him.
Narrated Abu Marhab: That Abdur-Rahman bin Awf alighted in the grave of the Prophet صلی اللہ علیہ وسلم. He said: I still seem to see the four of them.
