“Hamzah Al-Aslami asked the Messenger of Allah ﷺ: ‘I am fasting, should I fast while traveling?’ The Messenger of Allah ﷺ said: ‘If you wish, then fast, and if you wish, then break your fast.’” (Using translation from Ibn Mājah 1662)
جَاءَ حَمْزَةُ بْنُ عَمْرٍو الْأَسْلَمِيُّ إِلَى رَسُولِ اللهِ ﷺ فَقَالَ إِنِّي كُنْتُ أَصُومُ يَعْنِي أَسْرُدُ الصَّوْمَ أَفَأَصُومُ فِي السَّفَرِ؟ قَالَ إِنْ شِئْتَ فَصُمْ وَإِنْ شِئْتَ فَأَفْطِرْ
