It was narrated from ‘Imran bin Husain that a man bit the hand of another man, who pulled his hand away, and the man’s front tooth (or front teeth) fell out. He complained about that to the Messenger of Allah صلی اللہ علیہ وآلہ وسلم th, and the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “What do you want? Do you want me to tell him to put his hand in your mouth, so that you can bite it like a stallion bites? Or, do you want to give him your hand so that he may bite it, then you can pull it away if you want?” (Sahih)
