On the Day of the battle of Khaibar, Messenger of Allah ﷺ made donkey's meat unlawful 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 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  

" On the Day of Khaibar, the Messenger of Allah ﷺ allowed us to eat the flesh of horses but he forbade us from the flesh of donkeys."  

أَطْعَمَنَا رَسُولُ اللَّهِ ﷺ يَوْمَ خَيْبَرَ لُحُومَ الْخَيْلِ وَنَهَانَا عَنْ لُحُومِ الْحُمُرِ  

The Messenger of Allah ﷺ forbade the flesh of domestic asses on the day of Khaibar, but permitted horse flesh.  

نَهَانَا رَسُولُ اللَّهِ ﷺ يَوْمَ خَيْبَرَ عَنْ لُحُومِ الْحُمُرِ وَأَذِنَ لَنَا فِي لُحُومِ الْخَيْلِ  

"The Messenger of Allah ﷺ allowed us to eat horse meat, and he forbade us from eating donkey meat." He said: There is something on this from Asma' bin Abi Bakr. Abu 'Eisa said: This Hadith is Hasan Sahih. This is how it was reported by more than one narrator, from 'Amr bin Dinar from Jabir. Hammad bin Zaid reported it from 'Amr bin Dinar from Muhammad bin 'Ali, from Jabir. The narration of Ibn 'Uyainah (no. 1793) is more correct. He said: I heard Muhammad saying: "Sufyan bin 'Uyainah is better at memorizing than Hammad bin Zaid."  

أَطْعَمَنَا رَسُولُ اللَّهِ ﷺ لُحُومَ الْخَيْلِ وَنَهَانَا عَنْ لُحُومِ الْحُمُرِ قَالَ وَفِي الْبَابِ عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ
