Musannaf Ibn Abi Shayba 18:53

Abu Bakr narrated to us, he said: Abbad bin al-Awwam narrated to us, from Sufyan bin Husayn, from Shu'bah bin Musawir, from Umar bin Abd al-Aziz, that the Messenger of Allah (may Allah bless him and grant him peace) decreed for the *mudihah* (a wound that exposes the bone) five camels, and he did not decree anything regarding other than that.
