Messenger of Allah ﷺ set out for Mecca in Ramadan and he fasted, and when he reached Al-Kadid, he broke his fast and the people (with him) broke their fast too. (Abu ʿAbdullah said, "Al-Kadid is a land covered with water between Usfan and Qudaid.")  

أَنَّ رَسُولَ اللَّهِ ﷺ خَرَجَ إِلَى مَكَّةَ فِي رَمَضَانَ فَصَامَ حَتَّى بَلَغَ الْكَدِيدَ أَفْطَرَ فَأَفْطَرَ النَّاسُ قَالَ أَبُو عَبْدِ اللَّهِ وَالْكَدِيدُ مَاءٌ بَيْنَ عُسْفَانَ وَقُدَيْدٍ  

Messenger of Allah ﷺ was on a journey and saw a crowd of people, and a man was being shaded (by them). He asked, "What is the matter?" They said, "He (the man) is fasting." The Prophet ﷺ said, "It is not righteousness that you fast on a journey."  

كَانَ رَسُولُ اللَّهِ ﷺ فِي سَفَرٍ فَرَأَى زِحَامًا وَرَجُلاً قَدْ ظُلِّلَ عَلَيْهِ فَقَالَ مَا هَذَا فَقَالُوا صَائِمٌ فَقَالَ لَيْسَ مِنَ الْبِرِّ الصَّوْمُ فِي السَّفَرِ  

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.  

كُنَّا نُسَافِرُ مَعَ النَّبِيِّ ﷺ فَلَمْ يَعِبِ الصَّائِمُ عَلَى الْمُفْطِرِ وَلاَ الْمُفْطِرُ عَلَى الصَّائِمِ
