Ya'qub bin Ibrahim bin Sa'd narrates it with his chain; at its end it says: He summoned Abu Wadi'ah bin Khidam, who was the heir of Salma bint Ya'ar, and said: This is the inheritance of your freed slave, so take it. Wadi'ah said: O Commander of the Believers! A woman of our tribe freed him as a sa'ibah (in the name of her parents), and Allah has made us independent of it; we have no need of it. So Sayyiduna Umar (may Allah be pleased with him) deposited it in the public treasury.
