The Book Pertaining to the Excellent Qualities of the Holy Prophet (may Peace be upon them) and His Companions (Kitab Al-Fada'il)
Muslim :: Book 30 : Hadith 5851
Abu Huraira reported that the Angel of Death was sent to Moses (peace be upon him) to inform of his Lord's summons. When he came, he (Moses) boxed him and his eye was knocked out. He (the Angel of Death) came back to the Lord and said: You sent me to a servant. who did not want to die. Allah restored his eye to its proper place (and revived his eyesight), and then said: Go back to him and tell him that if he wants life he must place his hand on the back of an ox, and he would be granted as many years of life as the number of hair covered by his hand. He (Moses) said: My Lord what would happen then He said: Then you must court death. He said: Let it be now. And he supplicated Allah to bring him close to the sacred land. Thereupon Allah's Messenger (may peace be upon him) said: If I were there, I would have shown you his grave beside the road at the red mound.
