أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا الْمُعْتَمِرُ، قَالَ سَمِعْتُ عُبَيْدَ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ اتَّخَذَ رَسُولُ اللَّهِ صلى الله عليه وسلم خَاتَمًا مِنْ ذَهَبٍ وَجَعَلَ فَصَّهُ مِنْ قِبَلِ كَفِّهِ فَاتَّخَذَ النَّاسُ خَوَاتِيمَ الذَّهَبِ فَأَلْقَى رَسُولُ اللَّهِ صلى الله عليه وسلم خَاتَمَهُ وَقَالَ ‏"‏ لاَ أَلْبَسُهُ أَبَدًا ‏"‏ ‏.‏ وَأَلْقَى النَّاسُ خَوَاتِيمَهُمْ ‏.‏

It was narrated that Ibn 'Umar said: "The Messenger of Allah [SAW] put on a ring of gold and put its stone toward his palm. Then the people started to wear rings of gold. Then the Messenger of Allah [SAW] threw away his ring and said: 'I will never wear it again,' and the people threw away their rings." Translation Not Available
