We went out on an expedition with the Messenger of Allah ﷺ during Ramadan. Some of us observed the fast and some of us broke it. Neither the observer of the fast had any grudge against one who broke it, nor the breaker of the fast had any grudge against one who had fasted They knew that he who had strength enough (to bear its rigour) fasted and that was good, and they also found that he who felt weakness (and could not bear the burden) broke it, and that was also good. (Using translation from Muslim 1116d)   

البيهقي:٨١٦٨أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللهِ الْحَافِظُ حدَّثَنِي أَبُو الْحُسَيْنِ مُحَمَّدُ بْنُ أَحْمَدَ بْنِ الْحَسَنِ الْمُعَاوِيُّ ثنا جَعْفَرُ بْنُ أَحْمَدَ بْنِ نَصْرٍ الْحَافِظُ ثنا عَمْرُو بْنُ زُرَارَةَ ثنا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ عَنِ الْجُرَيْرِيِّ عَنْ أَبِي نَضْرَةَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ

كُنَّا نَغْزُو مَعَ رَسُولِ اللهِ ﷺ فِي رَمَضَانَ فَمِنَّا الصَّائِمُ وَمِنَّا الْمُفْطِرُ فَلَا يَجِدُ الصَّائِمُ عَلَى الْمُفْطِرِ وَلَا الْمُفْطِرُ عَلَى الصَّائِمِ ثُمَّ يَرَوْنَ أَنَّ مَنْ وَجَدَ قُوَّةً فَصَامَ فَإِنَّ ذَلِكَ حَسَنٌ وَيَرَوْنَ أَنَّ مَنْ وَجَدَ ضَعْفًا فَأَفْطَرَ فَإِنَّ ذَلِكَ حَسَنٌ

"We were on a journey with the Messenger of Allah. Some of us were fasting and some of us broke their fast. The one who broke their fast had no objection to the one who fasted, and the one who fasted had no objection to the one who broke his fast. They saw that whoever had the strength to fast then that was good, and whoever was weak, then breaking it was better."  

Abū ʿĪsá said that this Ḥadīth is Ḥasan-Ṣaḥīḥ.
