Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) had a ring made of silver. It remained in the blessed hand of the Prophet (peace and blessings be upon him), then after him, it remained in the hand of Sayyiduna Abu Bakr (may Allah be pleased with him), after him in the hand of Sayyiduna Umar (may Allah be pleased with him), then in the hand of Sayyiduna Uthman (may Allah be pleased with him). The words "Muhammad Rasul Allah" were engraved on it.
