Sunan an-Nasa'i 2312
It was narrated from Abu Saeed and Jabir bin 'Abdullah:
That they traveled with the Messenger of Allah. Some fasted and some did not, and those who were fasting did not criticize those who were not, and those who were not fasting did not criticize those who were.
أَخْبَرَنِي أَيُّوبُ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنَا مَرْوَانُ، قَالَ حَدَّثَنَا عَاصِمٌ، عَنْ أَبِي نَضْرَةَ الْمُنْذِرِ، عَنْ أَبِي سَعِيدٍ، وَجَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّهُمَا سَافَرَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَيَصُومُ الصَّائِمُ وَيُفْطِرُ الْمُفْطِرُ وَلاَ يَعِيبُ الصَّائِمُ عَلَى الْمُفْطِرِ وَلاَ الْمُفْطِرُ عَلَى الصَّائِمِ ‏.‏
