During the Ghazwa of Khaibar, the Prophet ﷺ ordered us to throw away the meat of the donkeys whether it was still raw or cooked. He did not allow us to eat it later on.
أَمَرَنَا النَّبِيُّ ﷺ فِي غَزْوَةِ خَيْبَرَ أَنْ نُلْقِيَ الْحُمُرَ الأَهْلِيَّةَ نِيئَةً وَنَضِيجَةً ثُمَّ لَمْ يَأْمُرْنَا بِأَكْلِهِ بَعْدُ
Messenger of Allah ﷺ commanded us to throw away the flesh of domestic asses whether uncooked or cooked; he then never commanded us to eat that.
أَمَرَنَا رَسُولُ اللَّهِ ﷺ أَنْ نُلْقِيَ لُحُومَ الْحُمُرِ الأَهْلِيَّةِ نِيئَةً وَنَضِيجَةً ثُمَّ لَمْ يَأْمُرْنَا بِأَكْلِهِ
“The Messenger of Allah ﷺ commanded us to throw away the meat of domesticated donkeys, raw or cooked, then he did not say anything to us about it after that.”
أَمَرَنَا رَسُولُ اللَّهِ ﷺ أَنْ نُلْقِيَ لُحُومَ الْحُمُرِ الأَهْلِيَّةِ نِيئَةً وَنَضِيجَةً ثُمَّ لَمْ يَأْمُرْنَا بِهِ بَعْدُ
