حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ، حَدَّثَنَا أَبُو خَالِدٍ، عَنْ هِشَامٍ، عَنِ ابْنِ سِيرِينَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ إِذَا دُعِيَ أَحَدُكُمْ فَلْيُجِبْ فَإِنْ كَانَ مُفْطِرًا فَلْيَطْعَمْ وَإِنْ كَانَ صَائِمًا فَلْيُصَلِّ ‏" ‏ ‏.‏ قَالَ هِشَامٌ وَالصَّلاَةُ الدُّعَاءُ ‏.‏ قَالَ أَبُو دَاوُدَ رَوَاهُ حَفْصُ بْنُ غِيَاثٍ أَيْضًا عَنْ هِشَامٍ ‏.‏
