Sunan Abi Dawud 1849
Abdullah ibn al-Harith reported on the authority of his father al-Harith:
(My father) al-Harith was the governor of at-Ta'if under the caliph Uthman. He prepared food for Uthman which contained birds and the flesh of wild ass. He sent it to Ali (may Allah be pleased with him). When the Messenger came to him he was beating leaves for camels and shaking them off with his hand. He said to him: Eat it. He replied: Give it to the people who are not in sacred state; we are wearing ihram. I adjure the people of Ashja' who are present here. Do you know that a man presented a wild ass to the Messenger of Allah (ﷺ) while he was in ihram? But he refused to eat from it. They said: Yes.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، حَدَّثَنَا سُلَيْمَانُ بْنُ كَثِيرٍ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، عَنْ أَبِيهِ، وَكَانَ الْحَارِثُ، خَلِيفَةَ عُثْمَانَ عَلَى الطَّائِفِ فَصَنَعَ لِعُثْمَانَ طَعَامًا فِيهِ مِنَ الْحَجَلِ وَالْبَعَاقِيبِ وَلَحْمِ الْوَحْشِ قَالَ فَبَعَثَ إِلَى عَلِيِّ بْنِ أَبِي طَالِبٍ فَجَاءَهُ الرَّسُولُ وَهُوَ يَخْبِطُ لأَبَاعِرَ لَهُ فَجَاءَهُ وَهُوَ يَنْفُضُ الْخَبَطَ عَنْ يَدِهِ فَقَالُوا لَهُ كُلْ ‏.‏ فَقَالَ أَطْعِمُوهُ قَوْمًا حَلاَلاً فَإِنَّا حُرُمٌ ‏.‏ فَقَالَ عَلِيٌّ رضى الله عنه أَنْشُدُ اللَّهَ مَنْ كَانَ هَا هُنَا مِنْ أَشْجَعَ أَتَعْلَمُونَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَهْدَى إِلَيْهِ رَجُلٌ حِمَارَ وَحْشٍ وَهُوَ مُحْرِمٌ فَأَبَى أَنْ يَأْكُلَهُ قَالُوا نَعَمْ ‏.‏
