Sayyiduna Ibn Umar (may Allah be pleased with them) narrates that the Messenger of Allah (peace and blessings be upon him) had a ring made of silver, and it was in his hand. Then it remained in the hand of Sayyiduna Abu Bakr (may Allah be pleased with him), then it remained in the hand of Sayyiduna Umar (may Allah be pleased with him), then it remained in the hand of Sayyiduna Uthman (may Allah be pleased with him), until it fell from him into the well of Aris. The inscription on that ring was: "Muhammad, Messenger of Allah" (peace and blessings be upon him).
