"I said: 'O Prophet of Allah, I am a man who fasts continually, so should I fast while traveling?' He said: 'If you wish then fast, and if you wish then do not fast."' (Using translation from Nasāʾī 2301)
قُلْتُ يَا نَبِيَّ اللهِ إِنِّي رَجُلٌ أَسْرُدُ الصَّوْمَ أَفَأَصُومُ فِي السَّفَرِ؟ قَالَ «إِنْ شِئْتَ فَصُمْ وَإِنْ شِئْتَ فَأَفْطِرْ»
