الشمائل المحمدية

Ibn 'Umar said: “Allah’s Messenger (Allah bless him and give him peace) chose a signet ring of silver, so it was in his possession. Then it was in the possession of Abu Bakr and the possession of 'Umar. Then it was in the possession of 'Uthman, until it fell into the well of Aris. Its engraved inscription was: ‘Muhammad is the Messenger of Allah.”
