Narrated Sahl: A woman came to the Prophet and said, "I have come to present myself to you (for marriage)." She kept standing for a long period during which period the Prophet looked at her carefully. When she stayed for a Long period, a man said to the Prophet "If you are not in need of her, then marry her to me." The Prophet said, "Have you got anything to give her (as Mahr)?" The man said, "No." The Prophet said, "Go (to your house) and search for something." The man went and came back to say, "By Allah, I could not find anything." The Prophet said, "Go again and search for something, even if it be an iron ring." He went again and came back saying, "No, by Allah, I could not get even an iron ring." The man had only an Izar and had no Rida' (upper garment). He said, "I will give her my Izar as Mahr." On that the Prophet said, "Your Izar? If she wears it, nothing of it will remain on you, and if you wear it nothing of it will be on her" The man went aside and sat down When the Prophet saw him leaving (after a while), he called back and asked. "How much Qur'an do you know (by heart)? He said, 'I know such and such Suras," naming some Suras. The Prophet said, "I marry her to you for the amount of Qur'an you know (by heart).

Narrated Anas bin Malik: Allah's Apostle wanted to write a letter to a group of people or some non-Arabs. It was said to him, "They do not accept any letter unless it is stamped." So the Prophet had a silver ring made for himself, and on it was engraved: 'Muhammad, the Apostle of Allah'. .. as if I am now looking at the glitter of the ring on the finger (or in the palm) of the Prophet .

Narrated Ibn `Umar: Allah's Apostle had a silver ring made for himself and it was worn by him on his hand. Afterwards it was worn by Abu Bakr, and then by `Umar, and then by `Uthman till it fell in the Aris well. (On that ring) was engraved: 'Muhammad, the Apostle of Allah."

Narrated Anas: The Prophet got a ring made for himself and said, "I have got a ring made (for myself) and engraved a certain engraving on it so none of you should get such an engraving on his ring." I saw the glitter of the ring on his little finger.

Narrated Anas bin Malik: When the Prophet intended to write to the Byzantines, it was said to him, "Those people do not read your letter unless it is stamped." So the Prophet took a silver ring and got 'Muhammad, the Apostle of Allah' engraved on it .... as if I am now looking at its glitter in his hand.

Narrated `Abdullah: The Prophet had a golden ring made for himself, and when he wore it. he used to turn its stone toward the palm of his! hand. So the people too had gold rings made for themselves. The Prophet then ascended the pulpit, and after glorifying and praising Allah, he said, "I had it made for me, but now I will never wear it again." He threw it away, and then the people threw away their rings too. (Juwairiya, a subnarrator, said: I think Nafi' said that the Prophet was wearing the ring in his right hand.)

Narrated Anas bin Malik: Allah's Apostle took a silver ring and had 'Muhammad, the Apostle' of Allah' engraved on it. The Prophet then said (to us), 'I have a silver ring with 'Muhammad, the Apostle of Allah engraved on it, so none of you should have the same engraving on his ring."

Narrated Anas: that when Abu Bakr became the Caliph, he wrote a letter to him (and stamped it with the Prophet's ring) and the engraving of the ring was in three lines: Muhammad in one line, 'Apostle' in another line, and 'Allah' in a third line.

Anas added: The ring of the Prophet was in his hand, and after him, in Abu Bakr's hand, and then in `Umar's hand after Abu Bakr. When `Uthman was the Caliph, once he was sitting at the well of Aris. He removed the ring from his hand and while he was trifling with it, dropped into the well. We kept on going to the well with `Uthman for three days looking for the ring, and finally the well was drained, but the ring was not found.

And ‘A’ishah (may Allah be pleased with her) had gold rings.
