Musannaf Ibn Abi Shaybah 37834 — The words of Umar bin Abd al-Aziz

It is narrated from Talhah bin Yahya that Umar bin Abd al-Aziz used to send out couriers. The narrator says: A freed slave of Umar's mounted a man on a post horse without his permission. The narrator says: So he (may Allah have mercy on him) summoned him and said: Remain as you are until you assess its value, then deposit it in the public treasury.
