Someone came to Messenger of Allah ﷺs and said, "The donkeys have been eaten (by the Muslims)." The Prophet kept quiet. Then the man came again and said, "The donkeys have been eaten." The Prophet ﷺ kept quiet. The man came to him the third time and said, "The donkeys have been consumed." On that the Prophet ﷺ ordered an announcer to announce to the people, "Allah and His Apostle forbid you to eat the meat of donkeys." Then the cooking pots were upset while the meat was still boiling in them.  

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

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  

When it was the Day of Khaibar a visitor came and said: Messenger of Allah, the asses have been eaten. Then another came and said: Messenger of Allah, the asses are being destroyed. Then Messenger of Allah ﷺ commanded Abu Talha to make an announcement that Allah and His Messenger have prohibited you (from eating) of the flesh of (domestic) asses, for these are loathsome or impure. He (the narrator) said: The earthein pots were turned over along with what was in them.  

لَمَّا كَانَ يَوْمُ خَيْبَرَ جَاءَ جَاءٍ فَقَالَ يَا رَسُولَ اللَّهِ أُكِلَتِ الْحُمُرُ ثُمَّ جَاءَ آخَرُ فَقَالَ يَا رَسُولَ اللَّهِ أُفْنِيَتِ الْحُمُرُ فَأَمَرَ رَسُولُ اللَّهِ ﷺ أَبَا طَلْحَةَ فَنَادَى إِنَّ اللَّهَ وَرَسُولَهُ يَنْهَيَانِكُمْ عَنْ لُحُومِ الْحُمُرِ فَإِنَّهَا رِجْسٌ أَوْ نَجِسٌ قَالَ فَأُكْفِئَتِ الْقُدُورُ بِمَا فِيهَا  

[Machine] "A man came to the Prophet ﷺ with meat from Khaybar, and he asked him: 'Have you eaten the donkey meat twice?' The man replied: 'Yes, I have consumed donkey meat.' The Prophet then announced: 'Verily, Allah and His Messenger forbid you from consuming donkey meat, for it is impure.'"  

أَنَّ رَجُلًا أَتَى النَّبِيَّ ﷺ بِخَيْبَرَ فَقَالَ أَكَلْتُالْحُمُرَ مَرَّتَيْنِ قَالَ ثُمَّ جَاءَ فَقَالَ أَفْنَيْتُ الْحُمُرَ قَالَ فَنَادَى إِنَّ اللهَ وَرَسُولَهُ يَنْهَيَانِكُمْ عَنْ لُحُومِ الْحُمُرِ فَإِنَّهَا رِجْسٌ
