حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَيُّوبَ بْنِ مُوسَى، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، فِي هَذَا الْخَبَرِ عَنِ النَّبِيِّ ﷺ فَنَقَشَ فِيهِ " مُحَمَّدٌ رَسُولُ اللَّهِ " . وَقَالَ " لاَ يَنْقُشْ أَحَدٌ عَلَى نَقْشِ خَاتَمِي هَذَا " . ثُمَّ سَاقَ الْحَدِيثَ .
