حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ عَدِيِّ بْنِ ثَابِتٍ وَعَطَاءُ بْنُ السَّائِبِ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عَبَّاسٍ قَالَ رَفَعَهُ أَحَدُهُمَا إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ جِبْرِيلَ كَانَ يَدُسُّ فِي فَمِ فِرْعَوْنَ الطِّينَ مَخَافَةَ أَنْ يَقُولَ لَا إِلَهَ إِلَّا اللَّهُ
