The Prophet made the meat of donkeys unlawful on the day of the battle of Khaibar.

The Prophet reached Khaibar in the morning, while the people were coming out carrying their spades over their shoulders. When they saw him they said, "This is Muhammad and his army! Muhammad and his army!" So, they took refuge in the fort. The Prophet raised both his hands and said, "Allahu Akbar, Khaibar is ruined, for when we approach a nation (i.e. enemy to fight) then miserable is the morning of the warned ones." Then we found some donkeys which we (killed and) cooked: The announcer of the Prophet announced: "Allah and His Apostle forbid you to eat donkey's meat." So, all the pots including their contents were turned upside down.

In the evening of the day of the conquest of Khaibar, the army made fires (for cooking). The Prophet said, "For what have you made these fires?" They said, "For cooking the meat of domestic donkeys." He said, "Throw away what is in the cooking pots and break the pots." A man from the people got up and said, "Shall we throw the contents of the cooking pots and then wash the pots (instead of breaking them)?" The Prophet said, "Yes, you can do either.'
