حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، عَنْ أَبِيهِ، قَالَ لَمَّا حَضَرَتْ أَبَا طَالِبٍ الْوَفَاةُ جَاءَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ " قُلْ لاَ إِلَهَ إِلاَّ اللَّهُ كَلِمَةً. أُحَاجُّ لَكَ بِهَا عِنْدَ اللَّهِ ".
