Ash-Shama'il Al-Muhammadiyah, Book 11, Hadith 83 (English) ⓘ
Hazrat Ibn Umar radiallahu anhu says that Rasulullah sallallahu alayhe wasallam had a ring made of silver. He used it as a seal (Stamp) on letters etc., but did not wear it
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.
