Sayyiduna Zayd bin Thabit (may Allah be pleased with him) said: "The Messenger of Allah (peace and blessings be upon him) gave only three rulings: concerning the ammah (a wound reaching the membrane of the brain), the munaqqilah (a wound that breaks and displaces bone) and the mudihah (a wound that exposes the bone). For the ammah he fixed a blood-money of thirty-three, for the munaqqilah fifteen and for the mudihah five (camels). And the Messenger of Allah (peace and blessings be upon him) ruled, concerning the eye of an animal, a quarter of its price."
