It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that once the Prophet Muhammad (peace and blessings be upon him) saw a gold ring in the hand of a companion (may Allah be pleased with him). The Prophet (peace and blessings be upon him) turned his face away from him. He threw it away and had a ring made of iron. The Prophet (peace and blessings be upon him) said: "This is even worse than that; this is the adornment of the people of Hell." He threw that away and had a ring made of silver. The Prophet (peace and blessings be upon him) remained silent at this.
