It was narrated from Abu Saeed Ai-Khudri: “A man came from Al-Bahrain to the Prophet صلی اللہ علیہ وآلہ وسلم greeted him with Salam, but he did not return his greeting. He was wearing a gold ring on his hand, and was wearing a silken Jubbah. He took them off, then he greeted him with Salam, and he returned his greeting. Then he said: ‘Messenger of Allah صلی اللہ علیہ وآلہ وسلم, I came to you just now, and you turned away from me.’ He said: ‘You had a coal of fire on your hand.’ He said: ‘Then I have brought many coals.’ He said: ‘What you have brought I with you is no better for us than the stones of Al-Harrah, but it is a temporary convenience of this world.’ He said: ‘What should I use for a ring?’ He said: ‘A ring of iron or silver or brass.” (Hasan)
