1023 – Abu Bakr ibn Muhammad ibn ʿAmr ibn Hazm narrated—through his father, from his grandfather—that the Prophet ﷺ wrote to the people of Yemen, mentioning in that letter:

“Whoever deliberately kills a believer without right, after the evidence has been established, is subject to retaliation (qiṣāṣ), unless the heirs of the slain are content. For the taking of a life, the diya is one hundred camels; for the nose, when it is completely severed, the full diya; for the tongue, the full diya; for the two lips, the full diya; for the penis, the full diya; for the two testicles, the full diya; for the backbone, the full diya; for one leg, half the diya. For a maʾmūmah (a head wound that reaches the membrane), one-third of the diya; for a jāʾifah (a penetrating wound of the body cavity), one-third of the diya; for a munqilah (a displaced fracture), fifteen camels. For every finger of the hand or the foot, ten camels; for a tooth, five camels; for a muḍiḥah (a wound that exposes the bone), five camels. A man is put to death for [murdering] a woman, and for people who deal in gold the full diya is one thousand dinars.”

It was recorded by Abū Dāwūd in al-Marāsīl, as well as by al-Nasāʾī, Ibn Khuzaymah, Ibn al-Jārūd, Ibn Ḥibbān, and Aḥmad, though they disagreed over its authenticity.⦗1⦘
