Should a Muslim residing in a non-Muslim country fast with the Muslims of that country or with Saudi Arabia, given that determining the beginning of Ramadan in that country does not depend on sighting the moon and may differ from Saudi Arabia?

The majority of jurists hold that the divergence of moon sightings is not to be considered. Thus, when the sighting of the Ramadan crescent is confirmed in one land, fasting becomes obligatory for all Muslims, based on the Prophet's (peace be upon him) saying: "Fast when you see it (the crescent) and break your fast when you see it. If it is obscured from you, then complete the number of Sha'ban to thirty." Consequently, you are obligated to fast in accordance with those for whom the beginning of the month has been confirmed. Conversely, the Shafi'is and some Hanafis are of the opinion that each land has its own sighting. According to this view, residents in non-Muslim countries should seek the crescent and fast according to their own sighting. If they are unable to do so, they should adopt the opinion of the majority and fast with those for whom the beginning of the crescent has been confirmed, and they should not follow a government decision if it is not based on a legitimate religious ground.
