Yaala reported,

Ibn Jurayj reported from Ata, from Safwan bin Yala, from Yala that he hired a worker who got into a fight with another man. The man bit his hand, and when he pulled his hand away, the man's front tooth came out. The matter was brought before the Prophet ﷺ, who said, "Should he leave his hand for him to chew on like a stallion chews?"
