"On the Day of Khaibar we ate the flesh of horses, and onagers, but the Prophet forbade us (from eating) donkeys."(sahih) (Using translation from Nasāʾī 4343)  

أَكَلْنَا يَوْمَ خَيْبَرَ لُحُومَ الْخَيْلِ وَالْوَحْشِ «وَنَهَانَا النَّبِيُّ ﷺ عَنِ الْحِمَارِ»  

"While we were traveling with the Prophet in part of Athaya Ar-Rawha and they were in Ihram, we saw a wounded onager, the Messenger of Allah said: "Leave it, for soon the one who wounded it will come,' then a man from Bahz came, and he was the one who had wounded the onager. He said: 'O Messenger of Allah, it is up to you what you do with this onager,' The Messenger of Allah ordered Abu Bakr to distribute it among the people." (Using translation from Nasāʾī 4344)  

بَيْنَمَا نَحْنُ نَسِيرُ مَعَ رَسُولِ اللهِ ﷺ بِبَعْضِ أَثَايَا الرَّوْحَاءِ وَهُمْ حُرُمٌ إِذَا حِمَارٌ مَعْقُورٌ فَقَالَ رَسُولُ اللهِ ﷺ «دَعُوهُ فَيُوشِكُ صَاحِبُهُ أَنْ يَأْتِيَهُ» فَجَاءَ رَجُلٌ مِنْ بَهْزٍ هُوَ الَّذِي عَقَرَ الْحِمَارَ فَقَالَ يَا رَسُولَ اللهِ شَأْنُكُمْ هَذَا الْحِمَارُ «فَأَمَرَ رَسُولُ اللهِ ﷺ أَبَا بَكْرٍ فَقَسَمَهُ بَيْنَ النَّاسِ»  

he caught an onager and brought it to his companion's who were in Ihram whereas he was not, and they ate from it. Then they said to one another: "Let us ask the Messenger of Allah about it," So we asked him and he said:" You did well" Then he said to us: "Do you have anything left of it?" We said: "Yes." He said: "Give us some "So we brought him some, and he ate from it, while he was in Ihram. (Using translation from Nasāʾī 4345)  

أَصَابَ حِمَارًا وَحْشِيًّا فَأَتَى بِهِ أَصْحَابَهُ وَهُمْ مُحْرِمُونَ وَهُوَ حَلَالٌ فَأَكَلْنَا مِنْهُ فَقَالَ بَعْضُنَا لِبَعْضٍ لَوْ سَأَلْنَا رَسُولَ اللهِ ﷺ عَنْهُ فَسَأَلْنَاهُ فَقَالَ «قَدْ أَحْسَنْتُمْ» فَقَالَ لَنَا «هَلْ مَعَكُمْ مِنْهُ شَيْءٌ؟» قُلْنَا نَعَمْ قَالَ «فَأَهْدُوا لَنَا» قَالَ فَأَتَيْنَاهُ مِنْهُ فَأَكَلَ مِنْهُ وَهُوَ مُحْرِمٌ
