حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا حَمَّادٌ ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم 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 " .
Allah's Messenger (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."
