قَوْلُهُ تَعَالَى: {لَوْ أَنْفَقْتَ مَا فِي الْأَرْضِ جَمِيعًا مَا أَلَّفْتَ بَيْنَ قُلُوبِهِمْ} [الأنفال: 63]

الكبرى للنسائي:١١١٤٦ – أَخْبَرَنِي مُحَمَّدُ بْنُ آدَمَ بْنِ سُلَيْمَانَ عَنْ حَفْصٍ وَهُوَ ابْنُ غِيَاثٍ عَنْ فُضَيْلِ بْنِ غَزْوَانَ قَالَ ضَمَّنِي إِلَيْهِ أَبُو إِسْحَاقَ فَقَالَ إِنِّي لَأُحِبُّكَ فِي اللهِ حَدَّثَنِي أَبُو الْأَحْوَصِ عَنْ عَبْدِ اللهِ قَالَ
