Sayyidina lmran ibn Husayn narrated that a man bit another’s hand. He pulled his hand away and two of the biter’s teeth came off. They went to the Prophet (SAW) and he said, “One of you bites his brother as a camel bites. There is no diyat for you.” The verse was revealed after that: (and for wounds a like retaliation).
