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

حَدَّثَنِي يَحْيَى بْنُ يَحْيَى ، وَمُحَمَّدُ بْنُ رُمْحٍ ، قَالَا : أَخْبَرَنَا اللَّيْثُ . ح وحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، حَدَّثَنَا لَيْثٌ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ ، عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا أَنَّهُ أَخْبَرَهُ : " أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ عَامَ الْفَتْحِ فِي رَمَضَانَ ، فَصَامَ حَتَّى بَلَغَ الْكَدِيدَ ، ثُمَّ أَفْطَرَ " ، قَالَ : وَكَانَ صَحَابَةُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَّبِعُونَ الْأَحْدَثَ فَالْأَحْدَثَ مِنْ أَمْرِهِ ،
Ibn Abbas (RA) reported that the Messenger of Allah (ﷺ) went out during the month of Ramadan in the year of Victory (when Makkah was conquered) and was fasting till he reached Kadid (a canal situated at a distance of forty-two miles from Makkah) and he then broke the fast. And it was the habit of the Companions of the Messenger of Allah (ﷺ) to follow him in every new thing (or act). So they followed him also (in this matter).
