صَحِيحُ مُسْلِمٍ
Sahih Muslim 1113 b
كتاب الصيام
It is permissible to fast or not to fast during Ramadan for one who is travelling for no sinful purpose, if his journey is two stages or further. But it is better for the one who is able to fast without suffering any harm to do so, and the one for whom it is difficult may break the fast
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَعَمْرٌو النَّاقِدُ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ عَنْ سُفْيَانَ، عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ . مِثْلَهُ . قَالَ يَحْيَى قَالَ سُفْيَانُ لاَ أَدْرِي مِنْ قَوْلِ مَنْ هُوَ يَعْنِي وَكَانَ يُؤْخَذُ بِالآخِرِ مِنْ قَوْلِ رَسُولِ اللَّهِ صلى الله عليه وسلم .
