A man bit another man on the forearm. The bitten man jerked his arm away, and in doing so the biter's front tooth was pulled out. The matter was brought before the Prophet ﷺ, who dismissed any claim for compensation and said, "Did you intend to chew your brother's flesh the way a stallion chews?"
أخبرنا عمرو بن علي قال حدثنا يزيد قال حدثنا سعيد بن أبي عروبة عن قتادة عن زرارة بن أوفى
أن رجلا عض آخر على ذراعه فاجتذبها فانتزعت ثنيته فرفع ذلك إلى النبي ﷺ فأبطلها وقال أردت أن تقضم لحم أخيك كما يقضم الفحل
Bukhari narrated it in the Book of Blood Money, Chapter "If a man bit another and his front teeth fell out," Hadith 6892, and Muslim, Hadith 1673, from the hadith of Qatada with the same chain, and it is in Kubra, Hadith 6961.
