It is narrated from Hazrat Imran bin Husain (may Allah be pleased with him) that a man bit off another man's hand from a distance. When the bitten man pulled his hand away, the front teeth of the one who bit him broke and fell out. Both of them brought this dispute to the service of the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) declared it invalid and said, "One of you bites his brother like a bull; you will not receive any compensation."
