He saw a ring of silver on the hand of the Messenger of Allah [SAW] one day, and the people made and wore similar rings. Then the Prophet [SAW] threw his ring away and the people threw their rings away too. (Using translation from Nasāʾī 5291)
«أَنَّهُ رَأَى فِي يَدِ رَسُولِ اللهِ ﷺ خَاتَمًا مِنْ وَرِقٍ يَوْمًا وَاحِدًا فَصَنَعُوهُ فَلَبِسُوهُ فَطَرَحَ النَّبِيُّ ﷺ وَطَرَحَ النَّاسُ»
