Sahih Muslim | Book 24 | Hadith Number 5220

Narrated by Anas b. Malik
Anas b. Malik reported that one day he saw on the finger of Allah's Messenger (may peace be upon him) a silver ring, and the people also made silver rings and put them on. Then Allah's Apostle (may peace be upon him) threw his ring away, and so the people also threw away their rings.
