Ibn 'Umar Radiyallahu 'Anhu says. "Rasulullah Sallallahu 'Alayhi Wasallam kept his ring in his mubaarak hands (possession). Then it was kept by Abubakr Radiyallahu 'Anhu, then by 'Umar Radiyallahu 'Anhu. Thereafter by 'Uthmaan Radiyallahu 'Anhu. In his ('Uthmaan Radiyallahu 'Anhu's) time it fell in the Well of 'Arees. The inscription on this ring was 'Muhammadur Rasulullah"'.
حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ: حَدَّثَنَا عَبْدُ اللهِ بْنُ نُمَيْرٍ، قَالَ: حَدَّثَنَا عُبَيْدُ اللهِ بْنُ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ: اتَّخَذَ رَسُولُ اللهِ صلى الله عليه وسلم، خَاتَمًا مِنْ وَرِقٍ، فَكَانَ فِي يَدِهِ ثُمَّ كَانَ فِي يَدِ أَبِي بَكْرٍ، وَيَدِ عُمَرَ، ثُمَّ كَانَ فِي يَدِ عُثْمَانَ، حَتَّى وَقَعَ فِي بِئْرِ أَرِيسٍ، نَقْشُهُ: مُحَمَّدٌ رَسُولُ اللهِ.
