"The Prophet used to wear a ring of gold, then he discarded it, and put on a ring of silver on which was engraved (the words): 'Muhammad Rasul Allah.' He said: 'No one else should engrave his ring with an inscription like this ring of mine.' Then he put the stone toward the palm of his hand."

Sunan an-Nasa'i Book 48, Hadith 176 Next Hadith → The Messenger of Allah until he died, then on the hand of Abu Bakr until he died, then on the hand of 'Umar until he died. Then (it remained) on the hand of 'Uthman for the first six years of his duties, but when he had to write many letters, he gave it to a man from among Ansar who used to seal letters with it. Then the Ansari went out to a well belonging to 'Uthman and the ring fell. They looked for it but could not find it. He ordered that a similar ring be made and engraved (the words): "Muhammad Rasul Allah" on it.
