It was narrated that Anas bin Malik said:
“The Messenger of Allah ﷺ had a ring made for him, and he said: ‘I have had a ring made for me and had it engraved, and no one should make a ring with similar engraving.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ اصْطَنَعَ رَسُولُ اللَّهِ ـ ﷺ ـ خَاتَمًا فَقَالَ " إِنَّا قَدِ اصْطَنَعْنَا خَاتَمًا وَنَقَشْنَا فِيهِ نَقْشًا فَلاَ يَنْقُشَنَّ عَلَيْهِ أَحَدٌ " .
