Ibn Umar reported that Messenger of Allah ﷺ had made for himself a ring of silver, and he (wore it in his finger). then it was in Abu Bakr's finger. then it was in'Umar's finger. then it was in 'Uthman's finger. until it fell into the well of Aris and it had these words engraved upon it (Muhammad, Messenger of Allah). Ibn Numair narrated it with a slight variation of words.
اتَّخَذَ رَسُولُ اللَّهِ ﷺ خَاتَمًا مِنْ وَرِقٍ فَكَانَ فِي يَدِهِ ثُمَّ كَانَ فِي يَدِ أَبِي بَكْرٍ ثُمَّ كَانَ فِي يَدِ عُمَرَ ثُمَّ كَانَ فِي يَدِ عُثْمَانَ حَتَّى وَقَعَ مِنْهُ فِي بِئْرِ أَرِيسٍ نَقْشُهُ مُحَمَّدٌ رَسُولُ اللَّهِ قَالَ ابْنُ نُمَيْرٍ حَتَّى وَقَعَ فِي بِئْرِ وَلَمْ يَقُلْ مِنْهُ
