Anas b. Malik reported that the ring of Messenger of Allah ﷺ was made of silver and it had an Abyssinian stone in it.  

كَانَ خَاتِمُ رَسُولِ اللَّهِ ﷺ مِنْ وَرِقٍ وَكَانَ فَصُّهُ حَبَشِيًّا  

Anas b. Malik reported that Messenger of Allah ﷺ wore a silver ring on his right hand which had an Abyssinian stone in it, and he kept its stone towards the palm.  

أَنَّ رَسُولَ اللَّهِ ﷺ لَبِسَ خَاتَمَ فِضَّةٍ فِي يَمِينِهِ فِيهِ فَصٌّ حَبَشِيٌّ كَانَ يَجْعَلُ فَصَّهُ مِمَّا يَلِي كَفَّهُ  

This hadith has been narrated on the authority of Yunus b. Yazid with the same chain of transmitters.  

عَنْ يُونُسَ بْنِ يَزِيدَ بِهَذَا الإِسْنَادِ مِثْلَ حَدِيثِ طَلْحَةَ بْنِ يَحْيَى
