Abdullah bin 'Abbas reported that Allah's Messenger (ﷺ) saw a person wearing a gold signet ring in his hand. He (the Holy Prophet) pulled it off and threw it away, saying: One of you is wishing live coal from Hell. and putting it on his hand. It was said to the person after Allah's Messenger (ﷺ) had left: Take your signet ring (of gold) and derive benefit out of it. Whereupon he said: No, by Allah, I would never take it when Allah's Messenger (ﷺ) has thrown it away.

'Abdullah reported that Allah's Messenger (may peace be upol him) got fashioned a signet ring of gold but he kept its stone on the inner side of his palm as he wore it, so the people (following his example) got fashioned (such rings). Then one day as he sat on the pulpit he pulled it away saying: I wore this ring and kept its stone towards the inner side. He then threw it away, and said: By Allah, I will never wear it; so the people threw their rings away.
