Sunan an-Nasai
أَخْبَرَنَا الرَّبِيعُ بْنُ سُلَيْمَانَ، قَالَ أَنْبَأَنَا ابْنُ وَهْبٍ، قَالَ أَنْبَأَنَا عَمْرٌو، وَذَكَرَ، آخَرَ عَنْ أَبِي الأَسْوَدِ، عَنْ عُرْوَةَ، عَنْ أَبِي مُرَاوِحٍ، عَنْ حَمْزَةَ بْنِ عَمْرٍو، أَنَّهُ قَالَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم أَجِدُ فِيَّ قُوَّةً عَلَى الصِّيَامِ فِي السَّفَرِ فَهَلْ عَلَىَّ جُنَاحٌ قَالَ " هِيَ رُخْصَةٌ مِنَ اللَّهِ عَزَّ وَجَلَّ فَمَنْ أَخَذَ بِهَا فَحَسَنٌ وَمَنْ أَحَبَّ أَنْ يَصُومَ فَلاَ جُنَاحَ عَلَيْهِ " .
It was narrated from Hamzah bin 'Amr that he said to the Messenger of Allah: "I feel able to fast while traveling; is there any sin on me?" He said: "It is a concession from Allah, the mighty and sublime, so whoever accepts it has done well, and whoever wants to fast, there is no sin on him."
