The Prophet ﷺ made the meat of donkeys unlawful on the day of the battle of Khaibar.  

عَنِ ابْنِ عُمَرَ ؓ نَهَى النَّبِيُّ ﷺ عَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ يَوْمَ خَيْبَرَ  

The Prophet ﷺ prohibited the eating of donkey's meat.  

نَهَى النَّبِيُّ ﷺ عَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ  

Messenger of Allah ﷺ prohibited Al-Mut'a marriage and the eating of donkey's meat in the year of the Khaibar battle.  

نَهَى رَسُولُ اللَّهِ ﷺ عَنِ الْمُتْعَةِ عَامَ خَيْبَرَ وَلُحُومِ حُمُرِ الإِنْسِيَّةِ  

The Prophet ﷺ prohibited the eating of donkey's meat on the day of the battle of Khaibar, and allowed the eating of horse flesh.  

نَهَى النَّبِيُّ ﷺ يَوْمَ خَيْبَرَ عَنْ لُحُومِ الْحُمُرِ وَرَخَّصَ فِي لُحُومِ الْخَيْلِ  

The Prophet ﷺ prohibited the eating of donkey's meat.  

عَنِ الْبَرَاءِ وَابْنِ أَبِي أَوْفَى ؓ قَالاَ نَهَى النَّبِيُّ ﷺ عَنْ لُحُومِ الْحُمُرِ  

Messenger of Allah ﷺ prohibited the eating of donkey's meat. Narrated Az-Zuhri: The Prophet ﷺ prohibited the eating of beasts having fangs.  

حَرَّمَ رَسُولُ اللَّهِ ﷺ لُحُومَ الْحُمُرِ الأَهْلِيَّةِ  

Someone came to Messenger of Allah ﷺ and said, "The donkeys have been (slaughtered and) eaten. Another man came and said, "The donkeys have been destroyed." On that the Prophet ﷺ ordered a caller to announce to the people: Allah and His Apostle forbid you to eat the meat of donkeys, for it is impure.' Thus the pots were turned upside down while the (donkeys') meat was boiling in them.  

أَنَّ رَسُولَ اللَّهِ ﷺ جَاءَهُ جَاءٍ فَقَالَ أُكِلَتِ الْحُمُرُ ثُمَّ جَاءَهُ جَاءٍ فَقَالَ أُكِلَتِ الْحُمُرُ ثُمَّ جَاءَهُ جَاءٍ فَقَالَ أُفْنِيَتِ الْحُمُرُ فَأَمَرَ مُنَادِيًا فَنَادَى فِي النَّاسِ إِنَّ اللَّهَ وَرَسُولَهُ يَنْهَيَانِكُمْ عَنْ لُحُومِ الْحُمُرِ الأَهْلِيَّةِ فَإِنَّهَا رِجْسٌ فَأُكْفِئَتِ الْقُدُورُ وَإِنَّهَا لَتَفُورُ بِاللَّحْمِ  

I said to Jabir bin Zaid, "The people claim that Messenger of Allah ﷺ forbade the eating of donkey's meat." He said, "Al-Hakam bin ʿAmr Al-Ghifari used to say so when he was with us, but Ibn ʿAbbas, the great religious learned man, refused to give a final verdict and recited:-- 'Say: I find not in that which has been inspired to me anything forbidden to be eaten by one who wishes to eat it, unless it be carrion, blood poured forth or the flesh of swine...' (6.145)  

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْ حُمُرِ الأَهْلِيَّةِ فَقَالَ قَدْ كَانَ يَقُولُ ذَاكَ الْحَكَمُ بْنُ عَمْرٍو الْغِفَارِيُّ عِنْدَنَا بِالْبَصْرَةِ وَلَكِنْ أَبَى ذَاكَ الْبَحْرُ ابْنُ عَبَّاسٍ وَقَرَأَ {قُلْ لاَ أَجِدُ فِيمَا أُوحِيَ إِلَىَّ مُحَرَّمًا}
