It was narrated from Ibn 'Umar that:

The Messenger of Allah ﷺ had a ring made of gold and he used to wear it with the stone (Fass) against his palm, and the people did likewise. Then he sat on the Minbar and said: "I used to wear this ring and put its stone (Fass) on the inside." Then he threw it away and said: "By Allah, I will never wear it again." And the people threw their rings away.

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ ﷺ اصْطَنَعَ خَاتَمًا مِنْ ذَهَبٍ وَكَانَ يَلْبَسُهُ فَجَعَلَ فَصَّهُ فِي بَاطِنِ كَفِّهِ فَصَنَعَ النَّاسُ ثُمَّ إِنَّهُ جَلَسَ عَلَى الْمِنْبَرِ فَنَزَعَهُ وَقَالَ " إِنِّي كُنْتُ أَلْبَسُ هَذَا الْخَاتَمَ وَأَجْعَلُ فَصَّهُ مِنْ دَاخِلٍ " . فَرَمَى بِهِ ثُمَّ قَالَ " وَاللَّهِ لاَ أَلْبَسُهُ أَبَدًا " . فَنَبَذَ النَّاسُ خَوَاتِيمَهُمْ .
