It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) had a ring made of gold. He would turn its stone towards the palm of his hand. The people also had rings made. Upon this, the Prophet (peace and blessings be upon him) threw it away, and the people also removed and threw away their rings. Then the Prophet (peace and blessings be upon him) had a ring made of silver, with which he would seal (letters), but he would not wear it.
