It was narrated from 'Imran bin Husain that a man bit another man on the forearm: 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?
It was narrated that 'Imran bin Husain said: Ya'la fought with a man, and one of them bit the other, who pulled his hand away from his mouth, and a front tooth fell out. They referred their dispute to the Messenger of Allah and he said: 'Would one of you bite his brother as a stallion bites? There is no Diyah for that.
It was narrated from 'Imran bin Husain that: Ya'la said, concerning the one who bit (another), and his front tooth fell out, that the Prophet said: There is no Diyah for you. (Sahih )
It was narrated from 'Imran bin Husain that: 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.
