What is the reason for the difference between the Umm Al-Qura Calendar and the Muslim World League in determining the times of Fajr and Isha, and which is the reliable reference for Muslims residing in Finland, and what does the phrase "There are two types of calculation methods: the first is 'standard' Maliki, Shafi'i, Hanbali, and the second is Hanafi" mean?

The reason for the variation in prayer times goes back to astronomy specialists. A Muslim must follow a trustworthy person in knowing the entry of prayer time. If two trustworthy individuals differ on the time of Fajr, the default is that it has not yet entered, and it is permissible to eat and drink until Fajr becomes clear.

Ibn Uthaymeen, may Allah have mercy on him, said: "The cosmic signs have become subtle, and people rely on calendars. If the calendars issued by knowledgeable individuals differ, we prioritize the later one for all times, because the default is that the time has not yet entered. If he were to tell two people to observe Fajr, and one said Fajr has risen while the other said it has not, he would take the word of the second. The calendar issued by the most knowledgeable or most trustworthy person is preferred."

The difference between the Hanafis and the majority is not regarding the time of Fajr prayer, but rather the time of Asr prayer, which the Hanafis believe enters when the shadow of an object becomes twice its length, while the majority believes it enters when the shadow is equal to its length. They also differed on the time of Isha. The Hanafis believe it enters with the disappearance of the white twilight, while the majority believes it enters with the disappearance of the red twilight. A layperson follows a trustworthy scholar, and the fatwa is based on the opinion of the majority.
