It is narrated from Sayyiduna Amr bin Hazm (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent a letter to the people of Yemen, in which it was written: "In the name of Allah, the Most Gracious, the Most Merciful. This letter is from Muhammad, the Prophet of Allah (peace and blessings be upon him), to Shurahbil bin Abd Kulal, Harith bin Abd Kulal, Na’eem bin Abd Kulal, Qil Dhi Ra’een, Ma’afir, and Hamdan, that the blood money for killing a soul is one hundred camels."

Abu Bakr bin Amr bin Hazm narrated from his father, from his grandfather (Sayyiduna Amr bin Hazm, may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) wrote to the people of Yemen, in which it was written: "And for the nose, there is full blood money when it is cut off from the root, and for the tongue, lips, two testicles, and the private part, there is full blood money, and for the back and both eyes, there is also full blood money. For one foot, there is half blood money. For a wound to the brain and a wound to the abdomen, there is one-third blood money, and for a wound in which the bone is broken, there is blood money of fifteen camels."
