(78) باب صِفَةِ خَاتَمِ النَّبِيِّ صلى الله عليه وسلم وَنَقْشِهِ
It was narrated that Ibn 'Umar said:
"The Messenger of Allah [SAW] took a ring of gold and put it on, and the people started to wear gold rings too. The Messenger of Allah [SAW] said: 'I used to wear this ring, but I will never wear it again.' Then he threw it away, and the people threw their rings away."
