Musannaf Ibn Abi Shaybah 31033 — Book of the Judgments

Makhul said that the Messenger of Allah (peace and blessings be upon him) ruled, concerning a wound of the head or face that reaches the bone or goes beyond it, in this way: for a wound that reaches the bone there are five camels; for a wound that breaks the bone and displaces it from its place there are fifteen camels; for a wound that reaches the membrane of the brain he ruled one third of the full blood money; and for a wound that reaches inside the abdomen he likewise ruled one third of the blood money.
