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 Saʿid bin Jubair who said, 'He has made the eating of donkeys' meat illegal for ever.")  

سَمِعْتُ ابْنَ أَبِي أَوْفَى ؓ يَقُولُ أَصَابَتْنَا مَجَاعَةٌ لَيَالِيَ خَيْبَرَ فَلَمَّا كَانَ يَوْمُ خَيْبَرَ وَقَعْنَا فِي الْحُمُرِ الأَهْلِيَّةِ فَانْتَحَرْنَاهَا فَلَمَّا غَلَتِ الْقُدُورُ نَادَى مُنَادِي رَسُولِ اللَّهِ ﷺ اكْفَئُوا الْقُدُورَ فَلاَ تَطْعَمُوا مِنْ لُحُومِ الْحُمُرِ شَيْئًا قَالَ عَبْدُ اللَّهِ فَقُلْنَا إِنَّمَا نَهَى النَّبِيُّ ﷺ لأَنَّهَا لَمْ تُخَمَّسْ قَالَ وَقَالَ آخَرُونَ حَرَّمَهَا الْبَتَّةَ وَسَأَلْتُ سَعِيدَ بْنَ جُبَيْرٍ فَقَالَ حَرَّمَهَا الْبَتَّةَ  

I asked 'Abdullah b. Abu Aufa about (the lawfulness or unlawfulness of) the flesh of the domestic asses. He said: We experienced hunger on the Day of Khaibar as we were with the Messenger of Allah ﷺ. We found domestic asses in the exterior of Medina. We slaughtered them and our earthen pots were boiling when the announcer of the Messenger of Allah ﷺ made an announcement that the earthen pots should be turned upside down and nothing of the flesh of the domestic asses should be eaten. I said: What kind of prohibition is it that he (the Holy Prophet) has made? He said: We discussed it amongst -ourselves. Some of us aaid that it has been declared unlawful for ever, (whereas others said) it has been declared unlawful since one-fifth (of the booty) has not been given (to the treasury, as is legally required).  

أَصَابَتْنَا مَجَاعَةٌ يَوْمَ خَيْبَرَ وَنَحْنُ مَعَ رَسُولِ اللَّهِ ﷺ وَقَدْ أَصَبْنَا لِلْقَوْمِ حُمُرًا خَارِجَةً مِنَ الْمَدِينَةِ فَنَحَرْنَاهَا فَإِنَّ قُدُورَنَا لَتَغْلِي إِذْ نَادَى مُنَادِي رَسُولِ اللَّهِ ﷺ أَنِ اكْفَئُوا الْقُدُورَ وَلاَ تَطْعَمُوا مِنْ لُحُومِ الْحُمُرِ شَيْئًا فَقُلْتُ حَرَّمَهَا تَحْرِيمَ مَاذَا قَالَ تَحَدَّثْنَا بَيْنَنَا فَقُلْنَا حَرَّمَهَا أَلْبَتَّةَ وَحَرَّمَهَا مِنْ أَجْلِ أَنَّهَا لَمْ تُخَمَّسْ  

I heard Abdullah b. Abu Aufa say: We were smitten with hunger during the nights of Khaibar. On the Day of Khaibar, we fell upon domestic asses and we slaughtered them, and when our earthen pots boiled with them, the announcer of Messenger of Allah ﷺ made an annoancement that the earthen pots should be turned over, and nothing should be eaten of the flesh of the domestic asses. Some of the people said that Messenger of Allah ﷺ had forbidden (the use of this flesh) for one-fifth (due to the State) has not been paid, while others said: He prohibited it for ever.  

سَمِعْتُ عَبْدَ اللَّهِ بْنَ أَبِي أَوْفَى يَقُولُ أَصَابَتْنَا مَجَاعَةٌ لَيَالِيَ خَيْبَرَ فَلَمَّا كَانَ يَوْمُ خَيْبَرَ وَقَعْنَا فِي الْحُمُرِ الأَهْلِيَّةِ فَانْتَحَرْنَاهَا فَلَمَّا غَلَتْ بِهَا الْقُدُورُ نَادَى مُنَادِي رَسُولِ اللَّهِ ﷺ أَنِ اكْفَئُوا الْقُدُورَ وَلاَ تَأْكُلُوا مِنْ لُحُومِ الْحُمُرِ شَيْئًا قَالَ فَقَالَ نَاسٌ إِنَّمَا نَهَى عَنْهَا رَسُولُ اللَّهِ ﷺ لأَنَّهَا لَمْ تُخَمَّسْ وَقَالَ آخَرُونَ نَهَى عَنْهَا أَلْبَتَّةَ
