(4) باب الصَّائِلُ عَلَى نَفْسِ الإِنْسَانِ أَوْ عُضْوِهِ إِذَا دَفَعَهُ الْمَصُولُ عَلَيْهِ فَأَتْلَفَ نَفْسَهُ أَوْ عُضْوَهَ لاَ ضَمَانَ عَلَيْهِ
'Imran b. Husain reported that a person bit the hand of a person. He withdrew his hand and his foretooth or foreteeth fell down. He (the man who lost his teeth) referred the matter to Allah's Messenger (ﷺ) and he said, What do you want me to do? Do you ask me that I should order him to put his hand in your mouth, and you should bite it as the camel bites? (If you want retaliation, then the only way out is) that you put your hand in his mouth (allow him) to bite that and then draw it away.
