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 1118
This hadith is listed as number 2620 in Maktaba Shamila
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، أَخْبَرَنَا أَبُو خَيْثَمَةَ ، عَنْ حُمَيْدٍ ، قَالَ : سُئِلَ أَنَسٌ رَضِيَ اللَّهُ عَنْ صَوْمِ رَمَضَانَ فِي السَّفَرِ ، فَقَالَ : " سَافَرْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فِي رَمَضَانَ فَلَمْ يَعِبْ الصَّائِمُ عَلَى الْمُفْطِرِ ، وَلَا الْمُفْطِرُ عَلَى الصَّائِمِ " .
Humaid reported that Anas (RA) was asked about fasting during Ramadan while travelling. He said: We travelled with the Messenger of Allah (ﷺ) during the month of Ramadan, but neither the observer of the fast found fault with the breaker of the fast, nor the breaker of the fast found fault with the observer of the fast.
