Is the sighting of the moon in one country sufficient for all Muslims?

The questioner : Your Excellency’s remarks on the sighting remind us of a question: Is the sighting in one country sufficient for all Muslims?

The Shaykh : That is what we see and what we call people to, but not everything a person hopes for is achieved. I mean, if the Islamic governments wanted to unify their fasting based on the sighting in one country, that would be permissible for them, and indeed obligatory. This is because the address in His saying (peace and blessings be upon him): is not an address to an individual or to the people of a specific country, but rather an address to the entire Ummah. It is very clear that applying this general address to all Muslims at that time was not possible; rather, it was applied to the extent of capability. Without a doubt, the scope of this capability has expanded in this era due to the means and inventions available today, which bring the far near and make the distant audible. If the states wish to unify their fasting, and as we mentioned earlier, we have all seen that, but before the word "on" in this phrase, I see that the people of each country should adhere to fasting with the announcement in their own country. If the announcement is based specifically on their own sighting or on the sighting of another country, they fast, and likewise they break their fast. As for the people of a country fasting based on the fasting of another country, while the people of that other country have not fasted or have not broken their fast, or vice versa, this increases, as it is said, the mud and the noise. I want to say that the disagreement currently exists; the Islamic countries do not fast at one time based on the sighting of one country, nor do they break their fast at one time. This is an undesirable difference. However, this difference increases and its harm worsens if the people of a country are divided in their fasting and breaking of their fast. Therefore, in this case, it is necessary to adhere to the unification that Allah (Mighty and Majestic) has established, so that these governments fast based on the sighting of one country and likewise break their fast.
Yes.
