Ibn `Abbas said, Allah's Messenger (ﷺ) fought the Ghazwa (i.e. battles of Al-Fath during Ramadan. Narrated Az-Zuhri: Ibn Al-Musaiyab (also) said the same. Ibn `Abbas added, The Prophet (ﷺ) fasted and when he reached Al-Kadid, a place where there is water between Kudaid and 'Usfan, he broke his fast and did not fast afterwards till the whole month had passed away.

The Prophet (ﷺ) left Medina (for Mecca) in the company of ten-thousand (Muslim warriors) in (the month of) Ramadan, and that was eight and a half years after his migration to Medina. He and the Muslims who were with him, proceeded on their way to Mecca. He was fasting and they were fasting, but when they reached a place called Al-Kadid which was a place of water between 'Usfan and Kudaid, he broke his fast and so did they. (Az-Zuhri said, One should take the last action of Allah's Messenger (ﷺ) and leave his early action (while taking a verdict.)

Allah's Messenger (ﷺ) set out towards Hunain in the month of Ramadan and some of the people were fasting while some others were not fasting, and when the Prophet (ﷺ) mounted his she-camel, he asked for a tumbler of milk or water and put it on the palm of his hand or on his she-camel and then the people looked at him; and those who were not fasting told those who were fasting, to break their fast (i.e. as the Prophet (ﷺ) had done so).

Ibn `Abbas said, Allah's Messenger (ﷺ) travelled in the month of Ramadan and he fasted till he reached (a place called) 'Usfan, then he asked for a tumbler of water and drank it by the daytime so that the people might see him. He broke his fast till he reached Mecca. Ibn `Abbas used to say, Allah's Apostle fasted and sometimes did not fast while traveling, so one may fast or may not (on journeys)
