Sunan an-Nasa'i, Hadith 5164 ⓘ
It was narrated that Ibn 'Umar said: "The Messenger of Allah [SAW] started to wear a gold ring, and the people started to wear gold rings. The Messenger of Allah [SAW] said: 'I was wearing this ring, but I will never wear it again.' He threw it away and the people threw their rings away.'"
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، عَنْ إِسْمَاعِيلَ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، قَالَ اتَّخَذَ رَسُولُ اللَّهِ صلى الله عليه وسلم خَاتَمَ الذَّهَبِ فَلَبِسَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَاتَّخَذَ النَّاسُ خَوَاتِيِمَ الذَّهَبِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنِّي كُنْتُ أَلْبَسُ هَذَا الْخَاتَمَ وَإِنِّي لَنْ أَلْبَسَهُ أَبَدًا " . فَنَبَذَهُ فَنَبَذَ النَّاسُ خَوَاتِيمَهُمْ .
