وَعَنْهُ أَيْضًا قَالَ اصْطَنَعَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ خَاتَمًا فَقَالَ إِنَّا قَدِ اصْطَنَعْنَا خَاتَمًا وَنَقَشْنَا فِيهِ نَقْشًا فَلَا يَنْقُشْ أَحَدٌ عَلَيْهِ
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) had a ring made and said: We have had a ring made and have engraved on it (the words "Muhammad, the Messenger of Allah"); none of you may have this inscription made.
