أَخْبَرَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ مُحَمَّدِ بْنِ كَثِيرٍ الْحَرَّانِيُّ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ حَفْصٍ، قَالَ حَدَّثَنَا مُوسَى بْنُ أَعْيَنَ، عَنْ عِيسَى بْنِ يُونُسَ، عَنِ الضَّحَّاكِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَطَاءٍ الْخُرَاسَانِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، قَالَ قَالَ عُمَرُ لِصُهَيْبٍ مَا لِي أَرَى عَلَيْكَ خَاتَمَ الذَّهَبِ قَالَ قَدْ رَآهُ مَنْ هُوَ خَيْرٌ مِنْكَ فَلَمْ يَعِبْهُ . قَالَ مَنْ هُوَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم .
