Musnad Ahmad 1744

Mis’ar told us: An old man of Fahm - he said: I think he was called Muhammad bin ‘AbdurRahman, and I think he was from the Hijaz - told us that he heard "Abdullah bin Ja"far tell Ibn azZubair, when a camel had been slaughtered for the people, that he heard the Messenger of Allah (ﷺ)say, when the people were putting meat in front of him: "The best meat is the meat from the back."
