What do you say about the difference in moonrise times regarding the sighting of the crescent moon?

The questioner : The Shaykh said: What do you say about the difference in moonrise times regarding the crescent moon?

The Shaykh : The scholars have differed greatly on this issue. In my view, the stronger position is the generality of the statement of the Prophet (peace and blessings be upon him): . His statement (peace and blessings be upon him): — as you see — is a comprehensive text that includes all those who are accountable. However, in the early periods, it was not feasible to convey the sighting of one who saw the crescent moon to establish the month; therefore, each region — and sometimes even each town — would fast based on the sighting in their own town. But now that the means to convey the sighting from east to west or from north to south have become available, I believe the stronger position is to apply this hadith, such that all Muslims fast. I do not say at the exact same time, but in a continuous sequence, due to the known difference in the rising and setting of the sun. However, they should not differ in determining the day on which the crescent moon was seen. If it is seen in the east, the people of the west should fast based on the sighting of the people of the east, a fortiori, and vice versa. It may be that the crescent moon was not seen in the east due to clouds, dust, or similar natural causes, but is seen clearly toward the west. Then, if the news of the sighting in the west reaches the people of the east, they must fast. If it reaches them during the day, for example, they must abstain from eating and drinking that day and make up another day. If it reaches them, for example, at the end of the day, it means they will be fasting the following day, and so on. Thus, his statement (peace and blessings be upon him): includes the entire Ummah. It is not reasonable, on the other hand, to divide the countries into regions, because this division may have originated from a policy that is not an Islamic policy, or there may be an old convention that distinguished some countries from others on a natural basis. But the ruling of Allah (Blessed and Exalted is He) must be comprehensive for all Muslims, to the extent that they are able to do so.
The time of fasting is not a matter like the times of prayer; the prayer times differ completely due to the rising, setting, and zenith of the sun. These times for the five prayers differ entirely from the issue of fasting, because fasting is for the sighting of the crescent moon to begin fasting, and then the sighting of the crescent moon to break the fast; it is one thing that does not repeat. Therefore, the stronger position, as it has become clear to me, is the opinion of Shaykh al-Islam Ibn Taymiyyah (may Allah have mercy on him) and many of the later researchers.
This is my opinion on the issue.
