Musannaf Ibn Abi Shaybah 25919 — Domestic donkeys

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him); he said: On the day of the Battle of Khaybar, the people slaughtered donkeys, and the meat began to boil in the pots. Then he (peace and blessings be upon him) ordered Sayyiduna Abu Talhah (may Allah be pleased with him), and he called out: Indeed, Allah Almighty and His Messenger (peace and blessings be upon him) have forbidden you domestic donkeys, for they are impure. So the pots were poured out.
