Messenger of Allah ﷺ took a silver ring and had 'Muhammad, the Apostle' of Allah' engraved on it. The Prophet then said (to us), 'I have a silver ring with 'Muhammad, the Messenger of Allah engraved on it, so none of you should have the same engraving on his ring."  

أَنَّ رَسُولَ اللَّهِ ﷺ اتَّخَذَ خَاتَمًا مِنْ فِضَّةٍ وَنَقَشَ فِيهِ مُحَمَّدٌ رَسُولُ اللَّهِ وَقَالَ إِنِّي اتَّخَذْتُ خَاتَمًا مِنْ وَرِقٍ وَنَقَشْتُ فِيهِ مُحَمَّدٌ رَسُولُ اللَّهِ فَلاَ يَنْقُشَنَّ أَحَدٌ عَلَى نَقْشِهِ  

[Machine] The Prophet Muhammad ﷺ had a silver ring engraved with the inscription "Muhammad, the Messenger of Allah." He said, "I have taken a silver ring and engraved on it 'Muhammad, the Messenger of Allah.' So do not engrave anything on it."  

أَنَّ رَسُولَ اللهِ ﷺ اتَّخَذَ خَاتَمًا مِنْ فِضَّةٍ وَنَقَشَ فِيهِ مُحَمَّدٌ رَسُولُ اللهِ فَقَالَ رَسُولُ اللهِ ﷺ إِنِّي قَدْ اتَّخَذْتُ خَاتَمًا مِنْ فِضَّةٍ وَنَقَشْتُ فِيهِ مُحَمَّدٌ رَسُولُ اللهِ فَلَا تَنْقُشُوا عَلَيْهِ  

"إِنَّا قد اتَّحذنا خاتما ونقشْنَا فيه نقشًا فلا يَنْقُشَنَّ أحدٌ على نقشِهِ".
