The Book of Games and the Animals which May be Slaughtered and the Aninals that Are to be Eaten (Kitab-us-Said wa'l-Dhaba'ih wa ma Yu'kalu min Al-Hayawan)

Muslim :: Book 21 : Hadith 4774

Ibn 'Abbas reported: I do not know whether Allah's Messenger (may peace be upon him) prohibited (the eating of the domestic ass) due to the fact that they were the beasts of burden for the people, so he (the Holy Prophet) did not like their beasts of burden to be destroyed (as a matter of expediency), or he prohibited the use of the flesh of domestic asses (not as an expediency but as a law of the Shari'ah) on the Day of Khaibar.
