Jabir said that in the course of a journey Allah's Messenger ﷺ saw a crowd and a man who had been put in the shade. On asking the reason and being told that he was fasting he said, “Fasting while on a journey is not a part of righteousness.” (Bukhari and Muslim.)

Anas said that in the course of a journey with the Prophet (ﷺ) when some of them were fasting and others broke their fast, they alighted at a stage on a hot day, and while those who fasted collapsed those who had broken their fast rose and set up the tents and watered the riding-beasts, whereupon Allah's Messenger ﷺ said, “Those who broke their fast have earned all the reward today.” (Bukhari and Muslim.)

Ibn ‘Abbas said Allah's Messenger ﷺ left Medina to go to Mecca and fasted till he reached ‘Usfan. He then called for water, and raising it aloft so that the people might see it, he broke his fast and did not resume it till he reached Mecca, and that was in Ramadan. Ibn ‘Abbas used to say, “Allah’s messenger has fasted and has broken his fast, so he who wishes may fast and he who wishes may break his fast.” (Bukhari and Muslim.) In a version by Muslim from Jabir it says that he drank after the afternoon prayer.

Anas b. Malik al-Ka‘bi reported Allah's Messenger ﷺ as saying, “Allah has remitted half the prayer to the traveller, and fasting to the traveller, the woman who is suckling an infant and the woman who is pregnant.” Abu Dawud, Tirmidhi, Nasa’i and Ibn Majah transmitted it.

He was told afterwards that some of the people had continued to fast, and said, “Those are the disobedient ones; those are the disobedient ones.” *A wadi two stages from Mecca on the way to Medina. Muslim transmitted it.

‘Abd ar-Rahman b. ‘Auf reported Allah's Messenger ﷺ as saying, “One who fasts in Ramadan while travelling is like one who breaks his fast when not travelling.” Ibn Majah transmitted it.

Hamza b. ‘Amr al-Aslami told Allah's Messenger ﷺ that he found himself strong enough to fast while travelling and asked whether it would be wrong for him to do so. He was told that licence had been given by Allah who is great and glorious, so that if anyone acted upon this he did well, but if anyone wished to fast he would not be guilty of sin. Muslim transmitted it.
