Sahih Muslim 1673 a
Imran b. Husain reported:
Ya'la b. Munya or Ibn Umayya fought with a person, and the one bit the hand of the other. And he tried to draw his hand from his mouth and thus his foreteeth ware pulled out. They referred their dispute to Allah's Apostle (ﷺ), whereupon he said: Does any one of you bite as the camel bites? So there is no blood-wit for it.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ زُرَارَةَ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، قَالَ قَاتَلَ يَعْلَى ابْنُ مُنْيَةَ أَوِ ابْنُ أُمَيَّةَ رَجُلاً فَعَضَّ أَحَدُهُمَا صَاحِبَهُ فَانْتَزَعَ يَدَهُ مِنْ فَمِهِ فَنَزَعَ ثَنِيَّتَهُ - وَقَالَ ابْنُ الْمُثَنَّى ثَنِيَّتَيْهِ - فَاخْتَصَمَا إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏
"‏ أَيَعَضُّ أَحَدُكُمْ كَمَا يَعَضُّ الْفَحْلُ لاَ دِيَةَ لَهُ ‏"‏ ‏.‏
