Arabic hadith text
أَخْبَرَنَا عَلِيُّ بْنُ الْحَسَنِ اللاَّنِيُّ، بِالْكُوفَةِ قَالَ حَدَّثَنَا عَبْدُ الرَّحِيمِ الرَّازِيُّ، عَنْ هِشَامٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، عَنْ حَمْزَةَ بْنِ عَمْرٍو، أَنَّهُ قَالَ يَا رَسُولَ اللَّهِ إِنِّي رَجُلٌ أَصُومُ أَفَأَصُومُ فِي السَّفَرِ قَالَ " إِنْ شِئْتَ فَصُمْ وَإِنْ شِئْتَ فَأَفْطِرْ "

It was narrated from 'Aishah that Hamzah bin 'Amr said
O Messenger of Allah, I am a man who fasts, so should I fast while traveling? He said: "If you wish then fast, and if you wish then do not fast."
