Sahih al-Bukhari 5865
Narrated `Abdullah:
Allah's Messenger (ﷺ) wore a gold or silver .. ring and placed its stone towards the palm of his hand. The 
people also started wearing gold rings like it, but when the Prophet (ﷺ) saw them wearing such rings, he 
threw away that golden ring and then wore a silver ring.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي نَافِعٌ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم اتَّخَذَ خَاتَمًا مِنْ ذَهَبٍ، وَجَعَلَ فَصَّهُ مِمَّا يَلِي كَفَّهُ، فَاتَّخَذَهُ النَّاسُ، فَرَمَى بِهِ، وَاتَّخَذَ خَاتَمًا مِنْ وَرِقٍ أَوْ فِضَّةٍ‏.‏
