We went out on an expedition with the Messenger of Allah ﷺ during Ramadan and neither the observer of the fast was found fault with for his fasting, nor the breaker of the fast for breaking it.
كُنَّا نُسَافِرُ مَعَ رَسُولِ اللَّهِ ﷺ فِي رَمَضَانَ فَمَا يُعَابُ عَلَى الصَّائِمِ صَوْمُهُ وَلاَ عَلَى الْمُفْطِرِ إِفْطَارُهُ
