Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said: When the arm is broken, there are 200 dirhams for it. And a man reports from Sayyiduna Umar (may Allah be pleased with him) that when the shin or the arm is broken, there are 20 dinars or two hiqqahs (three-year-old she-camels) for it, meaning when it heals without crookedness.

Ishaq bin al-Muhtafiz the Bedouin said that a man broke another man's shin, and Sayyiduna Umar (may Allah be pleased with him) ruled a diyah (blood money) of eight camels for it.
The Shaykh said: The narrations on this differ, and he made this ruling by his own judgement.

Ibn Shihab, Rabi'ah and Ibn Abi Farwah (may Allah have mercy on them) relate from the letter of Sayyiduna Mu'awiyah (may Allah be pleased with him) and the letter of Umar bin Abd al-Aziz (may Allah have mercy on him): "The Prophet (peace and blessings be upon him) did not fix anything for a hand broken by mistake except the bonesetter's fee." If it becomes straight but has crookedness or some defect, its value is assessed, and then the one who broke it pays that as a penalty.

Abu al-Zinad (may Allah have mercy on him) said: I heard the senior jurists of my time say: Every bone that is broken by mistake is to be set; if it becomes straight and there is no defect, then the offender owes only the cost of treatment. If, after being set, some defect or deficiency remains in it, then there is a diyah (blood money) upon him according to that defect, which people of understanding and insight will determine. Likewise is their view about a deep wound and all the wounds of the body: if they heal and no defect remains, only the costs of treatment are due from him.
