"The Prophet prohibited the Mut'ah with women, and the meat of domestic donkeys during (the campaign of) Khaibar."
أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ مُتْعَةِ النِّسَاءِ وَعَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ زَمَنَ خَيْبَرَ قَالَ وَفِي الْبَابِ عَنْ سَبْرَةَ الْجُهَنِيِّ وَأَبِي هُرَيْرَةَ
I said to Ibn ʿAbbas, "During the battle of Khaibar the Prophet ﷺ forbade (Nikah) Al-Mut'a and the eating of donkey's meat."
لاِبْنِ عَبَّاسٍ إِنَّ النَّبِيَّ ﷺ نَهَى عَنِ الْمُتْعَةِ وَعَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ زَمَنَ خَيْبَرَ
Fromt their father, that 'Ali said: "During the time of Khaibar, the Messenger of Allah ﷺ prohibited Mut'ah with women and eating the meat of domesticated donkeys.
نَهَى رَسُولُ اللَّهِ ﷺ عَنْ مُتْعَةِ النِّسَاءِ زَمَنَ خَيْبَرَ وَعَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ
'Ali b. AbiTalib reported that Messenger of Allah ﷺ prohibited on the Day of Khaibar the contracting of temporary marriage with women and the eating of the flesh of domestic asses. (Using translation from Muslim 1407a)
أَنَّ رَسُولَ اللَّهِ ﷺ «نَهَى عَنْ مُتْعَةِ النِّسَاءِ يَوْمَ خَيْبَرَ وَعَنْ أَكْلِ لُحُومِ الْحُمُرِ الْأَهْلِيَّةِ»
" عن على قال: نهى رسول الله ﷺ عن نكاح المتعة، وعن لحوم الحمر الأهلية زمن خيبر ".
