My hired worker fought with a man, and the man bit his hand. My worker pulled his hand from the man's mouth, knocking out his front tooth. He came to the Prophet ﷺ, who declared the tooth's loss without compensation and said, "Should he leave his hand in your mouth for you to chew on as a stallion chews?"
حدثنا يحيى بن سعيد عن ابن جريج قال أخبرني عطاء قال أخبرني
قاتل أجيري رجلا فعض يده فنزع يده من فيه فأندر ثنيته فأتى النبي ﷺ فأهدره وقال فيدع يده في فيك تقضمها كما يقضم الفحل
