حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، أَخْبَرَنَا أَبُو مُعَاوِيَةَ، عَنْ عَاصِمٍ، عَنْ مُوَرِّقٍ، عَنْ أَنَسٍ، - رضى الله عنه - قَالَ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم فِي السَّفَرِ فَمِنَّا الصَّائِمُ وَمِنَّا الْمُفْطِرُ - قَالَ - فَنَزَلْنَا مَنْزِلاً فِي يَوْمٍ حَارٍّ أَكْثَرُنَا ظِلاًّ صَاحِبُ الْكِسَاءِ وَمِنَّا مَنْ يَتَّقِي الشَّمْسَ بِيَدِهِ - قَالَ - فَسَقَطَ الصُّوَّامُ وَقَامَ الْمُفْطِرُونَ فَضَرَبُوا الأَبْنِيَةَ وَسَقَوُا الرِّكَابَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ ذَهَبَ الْمُفْطِرُونَ الْيَوْمَ بِالأَجْرِ ‏"‏ ‏.‏
Translation
Anas (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) was journeying (along with his Companions). Some of them had observed the fast whereas the others had broken it. Those who did not fast girded up their loins and worked, but the observers of the fast were too weak to work. Upon this he (the Messenger of Allah) said

Today the breakers of the fast have gone with the reward.
