أحمد:١٢٥٨٧ – حَدَّثَنَا إِبْرَاهِيمُ بْنُ مَهْدِيٍّ حَدَّثَنَا جَعْفَرُ بْنُ سُلَيْمَانَ قَالَ حَدَّثَنَا ثَابِتٌ الْبُنَانِيُّ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ

كَانَ رَسُولُ اللهِ ﷺ يَسْمَعُ بُكَاءَ الصَّبِيِّ مَعَ أُمِّهِ وَهُوَ فِي الصَّلَاةِ فَيَقْرَأُ بِالسُّورَةِ الْخَفِيفَةِ قَالَ جَعْفَرٌ أَوْ بِالسُّورَةِ الْقَصِيرَةِ
