حَدَّثَنَا يَحْيَى بْنُ حَمَّادٍ حَدَّثَنَا أَبُو عَوَانَةَ عَنْ أَبِي بِشْرٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ كَانَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَاتَمٌ مِنْ ذَهَبٍ كَانَ يُدْخِلُ فَصَّهُ فِي بَاطِنِ كَفِّهِ فَطَرَحَهُ ذَاتَ يَوْمٍ فَطَرَحَ أَصْحَابُهُ خَوَاتِيمَهُمْ ثُمَّ اتَّخَذَ خَاتَمًا مِنْ فِضَّةٍ وَكَانَ يَخْتِمُ بِهِ وَلَا يَلْبَسُهُ
مسند امام احمد بن حنبل · Hadith 5706
It was narrated that Ibn 'Umar said: The Prophet (PBUH) had a ring of gold and he used to wear its stone next to his palm. Then he threw it away one day and his companions threw away their rings. Then he acquired a ring of silver, which he used as a seal and did not wear.
