الكبرى للنسائي:٦٦٣ – أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ قَالَ حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ عَنْ يُونُسَ عَنِ ابْنِ سِيرِينَ قَالَ

حَدَّثَنِي بَعْضُ مَنْ صَلَّى مَعَ النَّبِيِّ ﷺ صَلَاةَ الصُّبْحِ فَلَمَّا قَالَ «سَمِعَ اللهُ لِمَنْ حَمِدَهُ» فِي الرَّكْعَةِ الثَّانِيَةِ قَامَ هُنَيَّهَةً
