Sahih al-Bukhari · Book 87: Blood Money (Ad-Diyat) · If somebody bites a man and has his tooth broken
Narrated Ya`la:
حَدَّثَنَا أَبُو عَاصِمٍ ، عَنِ ابْنِ جُرَيْجٍ ، عَنْ عَطَاءٍ ، عَنْ صَفْوَانَ بْنِ يَعْلَى ، عَنْ أَبِيهِ ، قَالَ خَرَجْتُ فِي غَزْوَةٍ، فَعَضَّ رَجُلٌ فَانْتَزَعَ ثَنِيَّتَهُ، فَأَبْطَلَهَا النَّبِيُّ صلى الله عليه وسلم.
I went out in one of the Ghazwa and a man bit another man and as a result, an incisor tooth of the former was pulled out. The Prophet (ﷺ) cancelled the case.
