Musannaf Ibn Abi Shaybah 39661 — The Battle of Khaybar

Abdullah bin Abi Salit narrates from his father, Sayyiduna Abu Salit (may Allah be pleased with him), who was a Companion who took part in Badr, that he said: The prohibition from the Prophet (peace and blessings be upon him) of eating domestic donkeys reached (us) while this very meat was boiling in the pots. Abu Salit said: So we tipped the pots over on their faces.
