Sahih al-Bukhari · Book 30 · Hadith 1947
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنَّا نُسَافِرُ مَعَ النَّبِيِّ صلى الله عليه وسلم فَلَمْ يَعِبِ الصَّائِمُ عَلَى الْمُفْطِرِ، وَلاَ الْمُفْطِرُ عَلَى الصَّائِمِ.
Narrated Anas bin Malik: We used to travel with the Prophet (ﷺ) and neither did the fasting persons criticize those who were not fasting, nor did those who were not fasting criticize the fasting ones.
