"I asked the Messenger of Allah about fasting while traveling. He said: 'If you wish to fast then fast, and if you wish not to fast then do not fast."' (Using translation from Nasāʾī 2296)
أَنَّهُ سَأَلَ رَسُولَ اللهِ ﷺ عَنِ الصَّوْمِ فِي السَّفَرِ قَالَ «إِنْ شِئْتَ أَنْ تَصُومَ فَصُمْ وَإِنْ شِئْتَ أَنْ تُفْطِرَ فَأَفْطِرْ»
