It has reached us in the hadith of Sayyiduna Amr bin Hazm (may Allah be pleased with him), from the Prophet (peace and blessings be upon him), both connected (mawsul) and mursal, that: "And for a munaqqilah (a wound by which the bone is displaced from its place) there are fifteen camels (as blood money)."
Hadith Referenceالسنن الكبرى للبيهقي / كتاب الديات / Q16204
Makhul (may Allah have mercy on him) says that the Messenger of Allah (peace and blessings be upon him) ruled concerning wounds: "For an exposed wound there are five camels, and for a tooth also five camels. For a head wound there are 15 camels; for a wound to the abdomen and for a head wound in which the bone becomes exposed there is one third of the blood money for a life, and for a life the full blood money. For an ear, a hand and a foot half the blood money, for the penis the full blood money, for the tongue the full blood money, and for the two testicles the blood money."
