Sayyiduna Ali (may Allah be pleased with him) said to Sayyiduna Ibn Abbas (may Allah be pleased with them): The Messenger of Allah (peace and blessings be upon him) forbade temporary marriage with women and the eating of domesticated donkey meat on the day of Khaybar.

Sayyiduna Anas bin Malik (may Allah be pleased with him) said that on the day of Khaybar, a companion stood up and said: "O Messenger of Allah! The donkeys have been eaten," or he said: "The donkeys have been finished (by eating them)." Then he said: "O Messenger of Allah! The donkeys have been finished," or "have been eaten." Thereupon, the Messenger of Allah (peace and blessings be upon him) ordered a companion to announce: "Indeed, Allah and His Messenger both forbid you from eating the meat of domesticated donkeys because they are impure."
