The ruling on the siege of a country in the context of multiple Islamic states

The questioner:
In the statement that the siege of one's country is a form of the obligation of jihad, regarding the definition of the country: Shaykh, if the Muslims are in more than one country, does the single designation apply, or does each country have its own people?

The Shaykh:
As it was in the beginning, the land of the Muslims was one. Yes, in the beginning, the entire land of the Muslims was one. So if any part of it was besieged, it became obligatory for all Muslims to defend against the enemy, because it was a siege of their country. But in recent times, when the lands became fragmented and the states multiplied, each state has its own ruling. Each state has its own ruling. It is obligatory for the people of that state, who are under the authority of one of the Muslim rulers, to defend their country if it is besieged. As for the lands of other Muslims, if they are able to provide them with reinforcements and assistance, it is obligatory for them to do so. Otherwise, this is not required if they are unable. Yes.

The presenter:
Meaning, if they are in more than one country, it does not fall under the category of obligation.

The Shaykh:
Yes, it is only in the category of recommendation and virtue. Yes.
