‘Abdallah b. Ja'far said the Prophet used to wear a signet-ring on his right hand.
Ibn Majah transmitted it, and Abu Dawud and Nasa’i transmitted it on ‘Ali’s authority.
‘Ali told that the Prophet, taking some silk and putting it in his right hand, and taking some gold and putting it in his left hand, said, “These are prohibited to the male members of my people.”
Ahmad, Abu Dawud and Nasa’i transmitted it.
‘Ali, pointing to the middle finger and the one next it, said, “God’s messenger forbade me to wear a signet-ring on this finger of mine or on this.”
Muslim transmitted it.
