Musannaf Ibn Abi Shaybah 35390 — The horseman: how much is he

Juwaybir said: We were in the region of Khurasan when Umar bin Abd al-Aziz wrote to us: It has reached us through trustworthy narrators that the Messenger of Allah (peace and blessings be upon him) gave the horseman three shares, two shares for his horse and one share for him, and gave the footman one share. And concerning horses he said: "The Arab, the muqrif and the birdhawn (different breeds of horses) are equal in this ruling."
