If a Muslim youth is being pursued and persecuted in his country for holding fast to his religion, is it permissible for him to remain in a land of disbelief?

The questioner : May Allah reward you with good. Your answer was extremely clear, but there are some inquiries we would like to ask you. May Allah reward you with good. If we say that there are Islamic schools, and this is something that no existing state can give us—an Islamic state—even the Dutch subjects are under the supervision of some of the brothers through whom we can purify their subjects of their poisoned ideas, such asThe Shaykh : Ahmad Salama, andThe Shaykh : 'Imad al-Din Bakri Ismail, and others.
Another matter is that some of the brothers who are there in the Netherlands are being persecuted by their countries, and so on. Are these justifications that can allow us to find them some leeway or an exit to reside in those countries?

The Shaykh : Your statement has two branches. I will clarify the first branch with you. The answer regarding the other branch is clear: because if some of the brothers—the state under whose rule they were living has hostile positions toward them—the earth of Allah is vast, so they can live in other Islamic lands. Therefore, we do not find an excuse for them to remain in those lands, and you have already known the ruling of the Shari'ah regarding remaining in them.
As for the other aspect, or the other branch, which is the first in your statement, it was not clear to me, so I ask for clarification.
