Ja'far bin Muhammad narrates from his father that the Messenger of Allah (peace and blessings be upon him) judged by an oath and a witness in matters of property, and in Kufah Ali (may Allah be pleased with him) also gave the same judgement, and during the caliphate of Umar (may Allah be pleased with him), Ubayy bin Ka'b (may Allah be pleased with him) also gave the same judgement.
