Not to criticize each other for observing Saum or not (on journeys)
Arabic hadith text
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنَّا نُسَافِرُ مَعَ النَّبِيِّ صلى الله عليه وسلمفَلَمْ يَعِبِ الصَّائِمُ عَلَى الْمُفْطِرِ، وَلاَ الْمُفْطِرُ عَلَى الصَّائِمِ.
Translation
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.
