Muwatta Malik, Book 49, Hadith 37 (USC-MSA) ⓘ

Yahya related to me from Malik from Abdullah ibn Dinar from 'Abdullah ibn 'Umar that the Messenger of Allah, may Allah bless him and grant him peace, used to wear a gold ring. Then the Messenger of Allah, may Allah bless him and grant him peace, stood up and threw it away and said, "I will never wear it." He said, "So the people threw away their rings."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَلْبَسُ خَاتَمًا مِنْ ذَهَبٍ ثُمَّ قَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَنَبَذَهُ وَقَالَ ‏ "‏ لاَ أَلْبَسُهُ أَبَدًا ‏" ‏ ‏.‏ قَالَ فَنَبَذَ النَّاسُ خَوَاتِيمَهُمْ ‏.‏
