The Messenger of Allah discarded it, and the people discarded their rings. Then he acquired a ring of silver with which he used to seal letters, but he did not wear it.
Sunan an-Nasa'i Book 48, Hadith 179
← Previous 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.

Salim narrated to Nafi' from his father, that the Prophet said: 'The angels do not accompany a caravan that has small bells with them.' How often do you see small bells with these people."
