'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 Messenger of Allah 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.  

أَنَّ رَجُلاً عَضَّ يَدَ رَجُلٍ فَانْتَزَعَ يَدَهُ فَسَقَطَتْ ثَنِيَّتُهُ أَوْ ثَنَايَاهُ فَاسْتَعْدَى رَسُولَ اللَّهِ ﷺ فَقَالَ رَسُولُ اللَّهِ ﷺ مَا تَأْمُرُنِي تَأْمُرُنِي أَنْ آمُرَهُ أَنْ يَدَعَ يَدَهُ فِي فِيكَ تَقْضَمُهَا كَمَا يَقْضَمُ الْفَحْلُ ادْفَعْ يَدَكَ حَتَّى يَعَضَّهَا ثُمَّ انْتَزِعْهَا  

a man bit the hand of another man, who pulled his hand away, and the man's front tooth (or from teeth) fell out. He complained about that to the Messenger of Allah, and the Messenger of Allah said: "What do you want? Do you want me to tell him to put his hand in your mouth, so that you can bite it like a stallion bites? Or, do you want to give him your hand so that he may bite it, then you can pull it away if you want?"  

أَنَّ رَجُلاً عَضَّ يَدَ رَجُلٍ فَانْتَزَعَ يَدَهُ فَسَقَطَتْ ثَنِيَّتُهُ أَوْ قَالَ ثَنَايَاهُ فَاسْتَعْدَى عَلَيْهِ رَسُولَ اللَّهِ ﷺ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ مَا تَأْمُرُنِي تَأْمُرُنِي أَنْ آمُرَهُ أَنْ يَدَعَ يَدَهُ فِي فِيكَ تَقْضَمُهَا كَمَا يَقْضَمُ الْفَحْلُ إِنْ شِئْتَ فَادْفَعْ إِلَيْهِ يَدَكَ حَتَّى يَقْضَمَهَا ثُمَّ انْتَزِعْهَا إِنْ شِئْتَ

أَنَّ رَجُلًا عَضَّ يَدَ رَجُلٍ فَانْتَزَعَ يَدَهُ فَسَقَطَتْ ثَنِيَّتُهُ أَوْ قَالَ ثَنَايَاهُ فَاسْتَعْدَى عَلَيْهِ رَسُولُ اللهِ ﷺ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «مَا تَأْمُرُنِي؟ تَأْمُرُنِي أَنْ آمُرَهُ؟ أَنْ يَدَعَ يَدَهُ فِي فِيكَ تَقْضَمُهَا كَمَا يَقْضَمُ الْفَحْلُ إِنْ شِئْتَ فَادْفَعْ إِلَيْهِ يَدَكَ حَتَّى يَقْضَمَهَا ثُمَّ انْتَزِعْهَا إِنْ شِئْتَ»
