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.
الْبَرَاءُ أَصَبْنَا يَوْمَ خَيْبَرَ حُمُرًا فَنَادَى مُنَادِي رَسُولِ اللَّهِ ﷺ أَنِ اكْفَئُوا الْقُدُورَ
That when they were in the company of the Prophet, they got some donkeys which they (slaughtered and) cooked. Then the announcer of the Prophet ﷺ said, "Turn the cooking pots upside down (i.e. throw out the meat).
أَنَّهُمْ كَانُوا مَعَ النَّبِيِّ ﷺ فَأَصَابُوا حُمُرًا فَطَبَخُوهَا فَنَادَى مُنَادِي النَّبِيِّ ﷺ: أَكْفِئُوا الْقُدُورَ۔
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. (Using translation from Muslim 1938b)
أَصَبْنَا يَوْمَ خَيْبَرَ حُمُرًا فَنَادَى مُنَادِي رَسُولِ اللهِ ﷺ أَنْ أَكْفِئُوا الْقُدُورَ
