Answered by Shaykh Amjad Rasheed
The new moon of Ramadan has been sighted in my country and I have made intentions to fast. Then, during the day, I traveled to another country where the moon had not been sighted. Can I break my fast, like the people in this country? Or do I have to complete my fast?
Our later scholars have differed in this matter. Allamah Al-Shihab Ibn Hajar, in his Tuhfa (383:3), opined that this traveler does not go with the people of the country he has traveled to and does not break his fast like them, but completes his fast. And al-Khateeb al-Shirbini and al-Shams al-Ramli have asserted that this traveler goes with the people of the country he has traveled to and, like them, breaks his fast, as has been transmitted from them by Abdul-Hamid in the super-commentaries on the Tuhfa.
