حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، قَالَ سَمِعْتُ الْعَبَّاسَ، يَقُولُ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّ أَبَا طَالِبٍ كَانَ يَحُوطُكَ وَيَنْصُرُكَ فَهَلْ نَفَعَهُ ذَلِكَ قَالَ " نَعَمْ وَجَدْتُهُ فِي غَمَرَاتٍ مِنَ النَّارِ فَأَخْرَجْتُهُ إِلَى ضَحْضَاحٍ " .
