Abu Ishaq Shaybani narrates: I heard Sayyiduna Abdullah bin Abu Awfa (may Allah be pleased with him) saying: On the occasion of the Battle of Khaybar, we found some donkeys outside the settlement, so we slaughtered them and their meat was being cooked in pots. In the meantime, an announcer from the Messenger of Allah (peace and blessings be upon him) made this announcement: "You people, turn over your pots along with whatever is in them!" So we turned them over even though they were boiling. (That is, the food was fully cooked.) The narrator named Abu Ishaq says: I met Sa'id bin Jubayr and mentioned this matter to him, so he said: These were the donkeys that used to eat filth, so the Messenger of Allah (peace and blessings be upon him) forbade them.
