Sahih Bukhari Volume 3, Book 28, Hadith 1824

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا صَالِحُ بْنُ كَيْسَانَ، عَنْ أَبِي مُحَمَّدٍ، نَافِعٍ مَوْلَى أَبِي قَتَادَةَ سَمِعَ أَبَا قَتَادَةَ ـ رضى الله عنه ـ قَالَ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم بِالْقَاحَةِ مِنَ الْمَدِينَةِ عَلَى ثَلاَثٍ ح‏.‏ وَحَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ حَدَّثَنَا سُفْيَانُ حَدَّثَنَا صَالِحُ بْنُ كَيْسَانَ عَنْ أَبِي مُحَمَّدٍ عَنْ أَبِي قَتَادَةَ ـ رضى الله عنه ـ قَالَ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم بِالْقَاحَةِ، وَمِنَّا الْمُحْرِمُ، وَمِنَّا غَيْرُ الْمُحْرِمِ، فَرَأَيْتُ أَصْحَابِي يَتَرَاءَوْنَ شَيْئًا فَنَظَرْتُ، فَإِذَا حِمَارُ وَحْشٍ ـ يَعْنِي وَقَعَ سَوْطُهُ ـ فَقَالُوا لاَ نُعِينُكَ عَلَيْهِ بِشَىْءٍ، إِنَّا مُحْرِمُونَ‏.‏ فَتَنَاوَلْتُهُ فَأَخَذْتُهُ، ثُمَّ أَتَيْتُ الْحِمَارَ مِنْ وَرَاءِ أَكَمَةٍ، فَعَقَرْتُهُ، فَأَتَيْتُ بِهِ أَصْحَابِي، فَقَالَ بَعْضُهُمْ كُلُوا‏.‏ وَقَالَ بَعْضُهُمْ لاَ تَأْكُلُوا‏.‏ فَأَتَيْتُ النَّبِيَّ صلى الله عليه وسلم وَهُوَ أَمَامَنَا، فَسَأَلْتُهُ فَقَالَ ‏"‏ كُلُوهُ حَلاَلٌ ‏"‏‏.‏ قَالَ لَنَا عَمْرٌو اذْهَبُوا إِلَى صَالِحٍ فَسَلُوهُ عَنْ هَذَا وَغَيْرِهِ، وَقَدِمَ عَلَيْنَا هَا هُنَا‏

Narrated By Abu Qatada : We were in the company of the Prophet at a place called Al-Qaha (which is at a distance of three stages of journey from Medina). Abu Qatada narrated through another group of narrators: We were in the company of the Prophet at a place called Al-Qaha and some of us had assumed Ihram while the others had not. I noticed that some of my companions were watching something, so I looked up and saw an onager. (I rode my horse and took the spear and whip) but my whip fell down (and I asked them to pick it up for me) but they said, "We will not help you by any means as we are in a state of Ihram." So, I picked up the whip myself and attacked the onager from behind a hillock and slaughtered it and brought it to my companions. Some of them said, "Eat it." While some others said, "Do not eat it." So, I went to the Prophet who was ahead of us and asked him about it, He replied, "Eat it as it is Halal (i.e. it is legal to eat it)."
