حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ أَبِي بِشْرٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم اتَّخَذَ خَاتَمًا مِنْ فِضَّةٍ، فَكَانَ يَخْتِمُ بِهِ وَلا يَلْبَسُهُ‏.‏

Ibn 'Umar said

"The Prophet (Allah bless him and give him peace) chose a signet ring of silver, so he used to seal [letters] with it, and he would not wear it.”
