4279. Narrated Tāwūs: Ibn 'Abbās said, "Allāh's Messenger ﷺ travelled in the month of Ramaḍān and he observed Saum (fast) till he reached (a place called) 'Usfān, then he asked for a tumbler of water and drank it by the daytime so that the people might see him. He broke his Saum (fast) till he reached Makkah." Ibn 'Abbās used to say, "Allāh's Messenger ﷺ observed Saum (fast) and sometimes did not observe Saum (fast) while travelling, so one may observe Saum (fast) or may not (on journeys)."
