The Messenger of Allah ﷺ wore a silver ring on his right hand, set with an Abyssinian stone, and he used to turn the stone toward the inside of his palm.
أن رسول الله ﷺ لبس خاتم فضة في يمينه، فيه فص حبشي، كان يجعل فصه مما يلي كفه.
Muslim narrated it in the Book of Clothing (62:2094) through several chains from Talha bin Yahya (he is the Ansari, then the Zurqi), from Yunus, from Ibn Shihab, from Anas, who said, and he mentioned it.
