“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.’” (Using translation from Ibn Mājah 3640)
اصْطَنَعَ رَسُولُ اللهِ ﷺ خَاتَمًا فَقَالَ إِنَّا قَدِ اصْطَنَعْنَا خَاتَمًا وَنَقَشْنَا فِيهِ نَقْشًا فَلَا يَنْقُشُ أَحَدٌ عَلَيْهِ
