Salama b. Akwa' reported:We went to Khaibar with Allah's Messenger (ﷺ). Then Allah granted (us) victory over them. On that very evening of the day when they had been granted victory, they lit many fires. Thereupon Allah's Messenger (ﷺ) said: What are those fires and what for those have been lit? They said: (These have been lit) for (cooking) the flesh. Thereupon he said: Of what flesh? They said: For the flesh of the domestic asses. Thereupon Allah's Messenger (may peace bo upon him) said: Throw that away and break them (the earthen pots in which the fiesa was being cooked). A person said: Messenger of Allah, should we throw it away and wash them (the cooking pots)? He said: You may do so.
وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبَّادٍ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا حَاتِمٌ، - وَهُوَ ابْنُ إِسْمَاعِيلَ - عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ، قَالَ خَرَجْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِلَى خَيْبَرَ ثُمَّ إِنَّ اللَّهَ فَتَحَهَا عَلَيْهِمْ فَلَمَّا أَمْسَى النَّاسُ الْيَوْمَ الَّذِي فُتِحَتْ عَلَيْهِمْ أَوْقَدُوا نِيرَانًا كَثِيرَةً فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَا هَذِهِ النِّيرَانُ عَلَى أَىِّ شَىْءٍ تُوقِدُونَ " قَالُوا عَلَى لَحْمٍ . قَالَ " عَلَى أَىِّ لَحْمٍ " . قَالُوا عَلَى لَحْمِ حُمُرٍ إِنْسِيَّةٍ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَهْرِيقُوهَا وَاكْسِرُوهَا " . فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ أَوْ نُهَرِيقُهَا وَنَغْسِلُهَا قَالَ " أَوْ ذَاكَ " .
