a man bit another man in the forearm, and his front tooth fell out, so he went to the Prophet and told him about that. He said: "Do you want to bite your brother's forearm as a stallion bites?" And he judged it to be invalid. (Using translation from Nasāʾī 4762)
أَنَّ رَجُلًا عَضَّ ذِرَاعَ رَجُلٍ فَانْتَزَعَ ثَنِيَّتَهُ فَانْطَلَقَ إِلَى النَّبِيِّ ﷺ فَذَكَرَ ذَلِكَ لَهُ فَقَالَ «أَرَدْتَ أَنْ تَقْضَمَ ذِرَاعَ أَخِيكَ كَمَا يَقْضَمُ الْفَحْلُ» فَأَبْطَلَهَا
he pulled it away and a front tooth fell out. The matter was referred to the Messenger of Allah and he canceled (the Diyah) and said: "Did you want to bite your brother's flesh as a stallion bites?"
أَنَّ رَجُلاً عَضَّ آخَرَ عَلَى ذِرَاعِهِ فَاجْتَذَبَهَا فَانْتَزَعَتْ ثَنِيَّتَهُ فَرُفِعَ ذَلِكَ إِلَى النَّبِيِّ ﷺ فَأَبْطَلَهَا وَقَالَ أَرَدْتَ أَنْ تَقْضَمَ لَحْمَ أَخِيكَ كَمَا يَقْضَمُ الْفَحْلُ

"عَنْ عمرانَ بن حصيْنٍ قَالَ: عَضَّ رجُلٌ رَجُلًا، فَانْتَزَعَ ثنيَتَهُ فَأبْطَلَهَا النَّبِىُّ ﷺ وَقَالَ: أرَدْتَ أَنْ تَقْضِمَ يد أخِيكَ كَمَا يَقْضِم الْفَحْلُ".
