كتاب الصيام
The Book of Fasting
باب جَوَازِ الصَّوْمِ وَالْفِطْرِ فِي شَهْرِ رَمَضَانَ لِلْمُسَافِرِ فِي غَيْرِ مَعْصِيَةٍ إِذَا كَانَ سَفَرُهُ مَرْحَلَتَيْنِ فَأَكْثَرَ وَأَنَّ الأَفْضَلَ لِمَنْ أَطَاقَهُ بِلاَ ضَرَرٍ أَنْ يَصُومَ وَلِمَنْ يَشُقُّ عَلَيْهِ أَنْ يُفْطِرَ:
Chapter: 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
Hadith 1116
This hadith is listed as number 2615 in Maktaba Shamila
حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ ، حَدَّثَنَا هَمَّامُ بْنُ يَحْيَى ، حَدَّثَنَا قَتَادَةُ ، عَنْ أَبِي نَضْرَةَ ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ : " غَزَوْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِسِتَّ عَشْرَةَ مَضَتْ مِنْ رَمَضَانَ ، فَمِنَّا مَنْ صَامَ ، وَمِنَّا مَنْ أَفْطَرَ ، فَلَمْ يَعِبْ الصَّائِمُ عَلَى الْمُفْطِرِ ، وَلَا الْمُفْطِرُ عَلَى الصَّائِمِ " ،
Abu Sa'id al-Khudri (RA) reported: We went out on an expedition with Allah's Messenger (ﷺ) on the 16th of Ramadan. Some of us fasted and some of us broke the fast. But neither the observer of the fast found fault with one who broke it, nor the breaker of the fast found fault with one who observed it.
