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

This hadith is listed as number 2621 in Maktaba Shamila
وحَدَّثَنَا وحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا أَبُو خَالِدٍ الْأَحْمَرُ ، عَنْ حُمَيْدٍ ، قَالَ : خَرَجْتُ فَصُمْتُ ، فَقَالُوا لِي : أَعِدْ ، قَالَ : فَقُلْتُ : إِنَّ أَنَسًا أَخْبَرَنِي : " أَنَّ أَصْحَابَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانُوا يُسَافِرُونَ ، فَلَا يَعِيبُ الصَّائِمُ عَلَى الْمُفْطِرِ ، وَلَا الْمُفْطِرُ عَلَى الصَّائِمِ " ، فَلَقِيتُ ابْنَ أَبِي مُلَيْكَةَ فَأَخْبَرَنِي ، عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا ، بِمِثْلِهِ .
Abu Khalid al-Ahmar narrated from Humaid who said: I went out and was fasting; they said to me: Break (it go back, repeat). He said that Anas reported that the Companions of the Messenger of Allah (ﷺ) used to set out on a journey and 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. (One of the narrators Humaid said): I met Ibn Abi Mulaikahh who informed me the same thing on the authority of 'A'isha.
