الكبرى للنسائي:٢٥٤٠أَخْبَرَنَا أَحْمَدُ بْنُ عِيسَى قَالَ حَدَّثَنَا ابْنُ وَهْبٍ عَنْ عَمْرِو بْنِ الْحَارِثِ عَنْ بُكَيْرٍ عَنْ سَعِيدِ بْنِ الْمُسَيِّبِ عَنْ أَبِي هُرَيْرَةَ

عَنِ النَّبِيِّ ﷺ قَالَ قَالَ اللهُ كُلُّ حَسَنَةٍ يَعْمَلُهَا ابْنُ آدَمَ فَلَهُ بِعَشْرِ أَمْثَالِهَا إِلَّا الصِّيَامَ لِي وَأَنَا أَجْزِي بِهِ
