Abu Saeed said:"We were traveling in Ramadan and among us were some who were fasting and some who were not. Those who were fasting did not criticize those who were not, and those who were not fasting did not criticize those who were."
أَخْبَرَنَا يَحْيَى بْنُ حَبِيبِ بْنِ عَرَبِيٍّ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ سَعِيدٍ الْجُرَيْرِيِّ، عَنْ أَبِي نَضْرَةَ، قَالَ حَدَّثَنَا أَبُو سَعِيدٍ، قَالَ كُنَّا نُسَافِرُ فِي رَمَضَانَ فَمِنَّا الصَّائِمُ وَمِنَّا الْمُفْطِرُ لاَ يَعِيبُ الصَّائِمُ عَلَى الْمُفْطِرِ وَلاَ يَعِيبُ الْمُفْطِرُ عَلَى الصَّائِمِ .
