It is narrated from Hazrat Imran bin Husain (may Allah be pleased with him) that Ya'la bin Munyah or Umayyah had a dispute with a man. One of them bit the other's hand, and when he pulled his hand away, the biter's front teeth 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) said: "One of you bites his brother like a bull; there is no blood money (compensation) for this."
