Musannaf Ibn Abi Shayba 20:15

Abu Bakr narrated to us, he said: Abbad bin al-Awwam narrated to us, from Sufyan bin Husayn, from Shaybah bin Musawir, he said: Umar bin Abd al-Aziz wrote, and his letter was read to us, that the Messenger of Allah (peace and blessings of Allah be upon him) decreed for the *mudihah* (a wound that exposes the bone) five camels, and he did not decree anything regarding other than that.
