إِذْ قَالَ لَهُمْ أَخُوهُمْ صَٰلِحٌ أَلَا تَتَّقُونَ
Surah Ash-Shu'araa(26:142)
Sahih al-Bukhari
One-fifth of Booty to the Cause of Allah (Khumus)
Chapter: The food gained as war booty in the battlefield
Narrated Ibn Abi `Aufa:
We were afflicted with hunger during the besiege of Khaibar, and when it was the day of (the battle of) Khaibar, we slaughtered the donkeys and when the pots got boiling (with their meat). Allah's Apostle made an announcement that all the pots should be upset and that nobody should eat anything of the meat of the donkeys. We thought that the Prophet (ﷺ) prohibited that because the Khumus had not been taken out of the booty (i.e. donkeys); other people said, "He prohibited eating them for ever." The sub-narrator added, "I asked Sa`id bin Jubair who said, 'He has made the eating of donkeys' meat illegal for ever.")
