On this father's authority, said: A servant of mine fought with a man and bit his hand and he drew away his hand. (One of) his front teeth fell out. So he came to the Prophet ﷺ who imposed no retaliation for his tooth, saying: Do you intend that he leaves his hand in your mouth so that you crunch it like a male camel ? He said: Ibn Abi Mulaikah told me on the authority of his grandfather that Abu Bakr (ra) imposed no retaliation on him for it, saying: May his tooth go away!  

قَاتَلَ أَجِيرٌ لِي رَجُلاً فَعَضَّ يَدَهُ فَانْتَزَعَهَا فَنَدَرَتْ ثَنِيَّتُهُ فَأَتَى النَّبِيَّ ﷺ فَأَهْدَرَهَا وَقَالَ أَتُرِيدُ أَنْ يَضَعَ يَدَهُ فِي فِيكَ تَقْضَمُهَا كَالْفَحْلِ قَالَ وَأَخْبَرَنِي ابْنُ أَبِي مُلَيْكَةَ عَنْ جَدِّهِ أَنَّ أَبَا بَكْرٍ ؓ أَهْدَرَهَا وَقَالَ بَعُدَتْ سِنُّهُ
