أَخْبَرَنَا أَحْمَدُ بْنُ حَفْصٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا إِبْرَاهِيمُ، عَنِ الْحَجَّاجِ، - هُوَ ابْنُ الْحَجَّاجِ - عَنْ قَتَادَةَ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُبَيْدٍ، عَنْ بَشِيرِ بْنِ نَهِيكٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ نَهَانِي رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ تَخَتُّمِ الذَّهَبِ ‏.‏

It was narrated from Abu Tha'labah Al-Khushani that

The Prophet [SAW] saw a gold ring on his hand, and he started to smack him with a stick that he had in his hand. When the Prophet [SAW] looked away, he threw it away. He said: "I think that he hurt you or we made you lose money."
