Abdullah bin Umar reported,

The Messenger of Allah ﷺ wore a gold ring for three days. When his companions saw it, gold rings spread among them, so he threw it away, and we do not know what became of it. Then he ordered a ring of silver to be made, and he commanded that it be engraved with, "Muhammad, Messenger of Allah."It remained on the hand of 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, and on the hand of Uthman for six years of his rule. When letters became numerous for him, he handed it over to a man from the Ansar, who would seal documents with it. The man from the Ansar went out to a well belonging to Uthman, and the ring fell in. They searched for it but could not find it. So Uthman ordered another ring just like it to be made, and it was engraved with, "Muhammad, Messenger of Allah."

عن ابن عمر

أن رسول الله ﷺ لبس خاتما من ذهب ثلاثة أيام، فلما رآه أصحابه فشت خواتيم الذهب، فرمي به، فلا ندري ما فعل، ثم أمر بخاتم من فضة، فأمر أن ينقش فيه: محمد رسول الله، وكان في يد رسول الله حتى مات، وفي يد أبي بكر حتى مات، وفي يد عمر حتى مات، وفي يد عثمان ست سنين من عمله، فلما كثرت عليه الكتب دفعه إلى رجل من الأنصار، فكان يختم به، فخرج الأنصاري إلى قليب لعثمان، فسقط، فالتمس فلم يوجد، فأمر بخاتم مثله، ونقش فيه: محمد مرسول الله.
