أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ أَبِي بِشْرٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم اتَّخَذَ خَاتَمًا مِنْ ذَهَبٍ وَكَانَ جَعَلَ فَصَّهُ فِي بَاطِنِ كَفِّهِ فَاتَّخَذَ النَّاسُ خَوَاتِيمَ مِنْ ذَهَبٍ فَطَرَحَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَطَرَحَ النَّاسُ خَوَاتِيمَهُمْ وَاتَّخَذَ خَاتَمًا مِنْ فِضَّةٍ فَكَانَ يَخْتِمُ بِهِ وَلاَ يَلْبَسُهُ ‏.‏

It was narrated from Ibn 'Umar that: The Messenger of Allah [SAW] put on a ring of gold, and he used to wear its stone (Fass) next to his palm. Then the people started to wear rings of gold too. Then the Messenger of Allah [SAW] threw it away, and the people threw their rings away too. Then he took a ring of silver and he used to seal letters with it, but he did not wear it.
