If a person attacks another person's life and limb, and the other defends himself and kills him or injures him, there is no penalty on him

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 ﷺ فَقَالَ " أَيَعَضُّ أَحَدُكُمْ كَمَا يَعَضُّ الْفَحْلُ لاَ دِيَةَ لَهُ " .

This hadith has been transmitted on the authority of Ya'la.

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ عَطَاءٍ، عَنِ ابْنِ يَعْلَى، عَنْ يَعْلَى، عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ .

'Imran b. Husain reported that a person bit the arm of another person;
he pulled it out and his foretooth fell down. This matter was taken to Allah's Apostle ﷺ, and he turned it down saying: Did you want to eat his flesh?

حَدَّثَنِي أَبُو غَسَّانَ الْمِسْمَعِيُّ، حَدَّثَنَا مُعَاذٌ، - يَعْنِي ابْنَ هِشَامٍ - حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ زُرَارَةَ بْنِ أَوْفَى، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، أَنَّ رَجُلاً، عَضَّ ذِرَاعَ رَجُلٍ فَجَذَبَهُ فَسَقَطَتْ ثَنِيَّتُهُ فَرُفِعَ إِلَى النَّبِيِّ ﷺ فَأَبْطَلَهُ وَقَالَ " أَرَدْتَ أَنْ تَأْكُلَ لَحْمَهُ " .

Safwan b. Ya'la reported that a person bit the arm of the servant of Ya'la b. Munya. He pulled it and his foretooth fell. The matter was referred to Allah's Apostle ﷺ and he turned it down and said: Did you intend to bite his hand, as the camel bites?

حَدَّثَنِي أَبُو غَسَّانَ الْمِسْمَعِيُّ، حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ بُدَيْلٍ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ، عَنْ صَفْوَانَ بْنِ يَعْلَى، أَنَّ أَجِيرًا، لِيَعْلَى ابْنِ مُنْيَةَ عَضَّ رَجُلٌ ذِرَاعَهُ فَجَذَبَهَا فَسَقَطَتْ ثَنِيَّتُهُ فَرُفِعَ إِلَى النَّبِيِّ ﷺ فَأَبْطَلَهَا وَقَالَ " أَرَدْتَ أَنْ تَقْضَمَهَا كَمَا يَقْضَمُ الْفَحْلُ " .

'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 month, 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.

حَدَّثَنَا أَحْمَدُ بْنُ عُثْمَانَ النَّوْفَلِيُّ، حَدَّثَنَا قُرَيْشُ بْنُ أَنَسٍ، عَنِ ابْنِ عَوْنٍ، عَنْ مُحَمَّدِ، بْنِ سِيرِينَ عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، 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 " .

Safwan b. Ya'la b. Munya reported on the authority of his father that there came to Allah's Apostle ﷺ a person who had bitten the hand of another person and who had withdrawn his hand (and as a result thereof) his foreteeth had fallen (those which had bitten). The Apostle of Allah ﷺ turned down his (claim), and said: Do you wish to bite as the camel bites?

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا عَطَاءٌ، عَنْ صَفْوَانَ بْنِ يَعْلَى ابْنِ، مُنْيَةَ عَنْ أَبِيهِ، قَالَ أَتَى النَّبِيَّ ﷺ رَجُلٌ وَقَدْ عَضَّ يَدَ رَجُلٍ فَانْتَزَعَ يَدَهُ فَسَقَطَتْ ثَنِيَّتَاهُ - يَعْنِي الَّذِي عَضَّهُ - قَالَ فَأَبْطَلَهَا النَّبِيُّ ﷺ وَقَالَ " أَرَدْتَ أَنْ تَقْضَمَهُ كَمَا يَقْضَمُ الْفَحْلُ " .

Safwan b. Ya'la b. Umayya thus reported from his father: I participated in the expedition to Tabuk with Allah's Apostle ﷺ. And Ya'la used to say: That was the most weighty of my deeds, in my opinion. Safwan said that Ya'la had stated: I had a servant;
he quarrelled with another person, and the one bit the hand of the other. ('Ata' said that Safwan had told him which one had bitten the hand of the other.) So he whose hand was bitten drew ill from (the mouth) of the one who had bitten it and (in this scuffle) one of his foreteeth was also drawn out. They both came to Allah's Apostle ﷺ and he declared his (claim for the compensation of) tooth as invalid.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي عَطَاءٌ، أَخْبَرَنِي صَفْوَانُ بْنُ يَعْلَى بْنِ أُمَيَّةَ، عَنْ أَبِيهِ، قَالَ غَزَوْتُ مَعَ النَّبِيِّ ﷺ غَزْوَةَ تَبُوكَ - قَالَ وَكَانَ يَعْلَى يَقُولُ تِلْكَ الْغَزْوَةُ أَوْثَقُ عَمَلِي عِنْدِي - فَقَالَ عَطَاءٌ قَالَ صَفْوَانُ قَالَ يَعْلَى كَانَ لِي أَجِيرٌ فَقَاتَلَ إِنْسَانًا فَعَضَّ أَحَدُهُمَا يَدَ الآخَرِ - قَالَ لَقَدْ أَخْبَرَنِي صَفْوَانُ أَيُّهُمَا عَضَّ الآخَرَ - فَانْتَزَعَ الْمَعْضُوضُ يَدَهُ مِنْ فِي الْعَاضِّ فَانْتَزَعَ إِحْدَى ثَنِيَّتَيْهِ فَأَتَيَا النَّبِيَّ ﷺ فَأَهْدَرَ ثَنِيَّتَهُ .
