Abu Nadra reported Abu Sa'id al. Khudri and Jabir b. Abdullah as saying:We travelled with the Messenger of Allah (ﷺ). The observer of the fast observed it, and the breaker of the fast broke it, but none of them found fault with each other

Abu Khalid al-Ahmar narrated from Humaid who said:I went out and was fasting; they said to me: Break (lit. 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 Mulaika who informed me the same thing on the authority of 'A'isha

Abu Sa'id al-Khudri (Allah be pleased with him) reported:We went out on an expedition with the Messenger of Allah (ﷺ) during Ramadan. Some of us observed the fast and some of us broke it. Neither the observer of the fast had any grudge against one who broke it, nor the breaker of the fast had any grudge against one who had fasted They knew that he who had strength enough (to bear its rigour) fasted and that was good, and they also found that he who felt weakness (and could not bear the burden) broke it, and that was also good
