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 has been narrated on the authority of Shu'ba with the same chain of transmitters but with this addition that he (the Holy Prophet) said: Take advantage of the concession of Allah Who Wanted it to you. When he (one of the narrators) asked him (the other one, Yabya b. Abi Kathar) he did not retain it in his mind.
