Breaking the fast for one who fasted in one country and then moved to another

Question:
He says: Honorable Shaykh, may Allah grant you success. If I fasted in a country where the crescent was sighted, and then I went to my country where they fasted based on their own sighting, or based on astronomical calculations after the sighting in the country where I fasted, what is the ruling on my breaking the fast? Do I break it with the country whose sighting I followed, or with my country where I arrived?

Answer:
No, not with the country you arrived in. Your ruling is the ruling of the country you arrived in. The Prophet (peace and blessings be upon him) said: and the Day of Sacrifice is the day you sacrifice. So do not break your fast while the people are fasting. Why would you go against the Muslims? Fast with them. Your ruling is their ruling, not the ruling of the country you traveled from, but rather the ruling of the country you arrived in. Do not go against the people. Yes.
