The prohibition of eating the meat of domesticated donkeys
وَحَدَّثَنَا ابْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، قَالَ قَالَ الْبَرَاءُ أَصَبْنَا يَوْمَ خَيْبَرَ حُمُرًا فَنَادَى مُنَادِي رَسُولِ اللَّهِ صلى الله عليه وسلم أَنِ اكْفَئُوا الْقُدُورَ .
Al-Bara' said: We found on the Day of Khaibar domestic asses, and the announcer of the Messenger of Allah (ﷺ) made an announcement that the earthen pots should be turned over.
