It is narrated from Hazrat Ya'la (may Allah be pleased with him) that I participated in the Battle of Tabuk with the Prophet (peace and blessings be upon him). In my view, this is an extremely strong deed. On the way, my laborer (tenant) got into a fight with a man. That man took his hand in his mouth and bit it. When he pulled his hand away, the man's tooth broke and fell out. He presented himself before the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) rejected his claim and said: Would he have left his hand in your mouth so that you could keep chewing it like a bull?
