حَدَّثَنَا نُصَيْرُ بْنُ الْفَرَجِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ اتَّخَذَ رَسُولُ اللَّهِ صلى الله عليه وسلم خَاتَمًا مِنْ ذَهَبٍ وَجَعَلَ فَصَّهُ مِمَّا يَلِي بَطْنَ كَفِّهِ وَنَقَشَ فِيهِ ‏"‏ مُحَمَّدٌ رَسُولُ اللَّهِ ‏"‏ ‏.‏ فَاتَّخَذَ النَّاسُ خَوَاتِمَ الذَّهَبِ فَلَمَّا رَآهُمْ قَدِ اتَّخَذُوهَا رَمَى بِهِ وَقَالَ ‏"‏ لاَ أَلْبَسُهُ أَبَدًا ‏"‏ ‏.‏ ثُمَّ اتَّخَذَ خَاتَمًا مِنْ فِضَّةٍ نَقَشَ فِيهِ ‏"‏ مُحَمَّدٌ رَسُولُ اللَّهِ ‏"‏ ‏.‏ ثُمَّ لَبِسَ الْخَاتَمَ بَعْدَهُ أَبُو بَكْرٍ ثُمَّ لَبِسَهُ بَعْدَ أَبِي بَكْرٍ عُمَرُ ثُمَّ لَبِسَهُ بَعْدَهُ عُثْمَانُ حَتَّى وَقَعَ فِي بِئْرِ أَرِيسَ ‏.‏ قَالَ أَبُو دَاوُدَ وَلَمْ يَخْتَلِفِ النَّاسُ عَلَى عُثْمَانَ حَتَّى سَقَطَ الْخَاتَمُ مِنْ يَدِهِ ‏.‏

Narrated Ibn 'Umar: The Messenger of Allah (PBUH) took a signet-ring of gold, and put the stone next the palm of his hand. He engraved on it "Muhammad, the Messenger of Allah". The people then took signet-rings of gold. When he saw that they had taken them (like his ring) he threw it away and said: I shall never wear it. He then fashioned a silver ring and engraved on it "Muhammad, the Messenger of Allah". Then Abu Bakr wore it after him, then 'Umar wore it after Abu Bakr, and the 'Uthman wore it after 'Umar till it fell down in a well called Aris. Abu Dawud said: The people did not disagree on 'Uthman till the signet-rin fell down from his hand. Translation Not Available
