What is the ruling on fasting and breaking the fast according to astronomical calculations?

Question : A questioner says: What is the ruling on fasting and breaking the fast according to astronomical calculations?

Answer : We, praise be to Allah, are in a country that follows what the Sunnah brought, which is the saying of the Prophet (peace and blessings be upon him) and in a hadith Here, the judges exercise the utmost care regarding the witness who testifies to the sighting of the crescent moon, so they cannot proceed with anything unless it is established from the Shari'ah perspective. The matter, praise be to Allah, is clear in these lands, but there are some Islamic countries that rule by astronomical calculations. These people should direct the question to the rulers who have the power to change things, to the scholars. Yes.
