أَخْبَرَنَا سَعِيدُ بْنُ يَعْقُوبَ الطَّالْقَانِيُّ، قَالَ حَدَّثَنَا خَالِدٌ، - وَهُوَ ابْنُ عَبْدِ اللَّهِ الْوَاسِطِيُّ - عَنْ أَبِي مَسْلَمَةَ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ، قَالَ كُنَّا نُسَافِرُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَمِنَّا الصَّائِمُ وَمِنَّا الْمُفْطِرُ وَلاَ يَعِيبُ الصَّائِمُ عَلَى الْمُفْطِرِ وَلاَ يَعِيبُ الْمُفْطِرُ عَلَى الصَّائِمِ .
