Abdullah bin Umar reported,

The Messenger of Allah ﷺ had a ring made of silver, which he wore on his hand. After him, it was on the hand of Abu Bakr, then on the hand of Umar, then on the hand of Uthman, until it eventually fell into the well of Aris. Its inscription read, "Muhammad, Messenger of Allah."
