A man came to the Prophet ﷺ after he had bitten another man's hand. The bitten man had pulled his hand away, causing the biter's two front teeth to fall out.The Prophet ﷺ dismissed his claim for compensation and said, "Did you want to chew him the way a stallion chews?"
أتى النبي ﷺ رجل، وقد عض يد رجل، فانتزع يده فسقطت ثنيتاه (يعني الذي عزه) قال: فأبطلها النبي ﷺ، وقال: أردت أن تقضمه كما يقضم الفحل؟
Bukhari reported it in the Book of Blood Money (6893), and Muslim reported it in the Book of Retribution (22:1674), both from the hadith of Ataa (that is, Ibn Abu Rabah), from Safwan bin Yaala, from his father, and he related it. The wording given is Muslim's. Bukhari's wording is abridged.In another version reported by Muslim (1673:18), Yaala bin Munya, or Ibn Umaya, fought with a man, and one of them bit the other. The one who was bitten pulled his hand from the other's mouth, and this pulled out the other's front tooth. They brought their dispute to the Prophet ﷺ, who said, "Does one of you bite as a stallion bites? He has no claim to blood money."Among the points of jurisprudence drawn from this hadith is that if a man defends himself and, as a result, a limb of the attacker is lost, there is no retaliation and no blood money owed, because the man has been commanded to defend himself. This is among the soundest positions held by the scholars, though some held that compensation is owed. The first position is more correct.
