Sahih Muslim , Book 34, Hadith 42 (In-Book) ⓘ
Al-Bara' said: We found on the Day of Khaibar domestic asses, and the announcer of the Messenger of Allah made an announcement that the earthen pots should be turned over.
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 .
