حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيلَ بْنِ سَمُرَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ الْحَسَنِ، حَدَّثَنَا أَبُو شَيْبَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ لَمَّا قُبِضَ إِبْرَاهِيمُ ابْنُ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ لَهُمُ النَّبِيُّ ـ صلى الله عليه وسلم ـ " لاَ تُدْرِجُوهُ فِي أَكْفَانِهِ حَتَّى أَنْظُرَ إِلَيْهِ " . فَأَتَاهُ فَانْكَبَّ عَلَيْهِ وَبَكَى .
