Is it permissible to remain and live in the lands of the disbelievers if one is able to manifest his religion among them and call them to it?

Question:
Is it permissible for us to remain and live in the lands of the disbelievers if we are able to manifest our religion among them and call to Islam?

Answer:
Migration is obligatory, and it is moving from the lands of disbelief to the lands of Islam to escape for the sake of the religion. It is obligatory and remains so until the Hour occurs. However, if a person is unable to migrate, he is excused on the condition that he holds fast to his religion, except for the weak among men, women, and children who are unable to find a way out or to find a path. This is the first case: the weak person who is unable to migrate remains, but on the condition that he holds fast to his religion and does not compromise on any part of it.
The second case is if he is on a religious mission, calling to Allah and teaching people what is good. In that case, he remains, because his staying has a stronger benefit, which is calling to Allah, teaching people what is good, and spreading goodness. Yes.
