Returning to the lands of disbelief after emigration

Question:
Honorable Shaykh, may Allah grant you success. This questioner says: A person emigrated from the lands of disbelief to the lands of Islam, but then he was compelled to return to the lands of disbelief and reside there. Does he thereby commit a major sin?

Answer:
No. If he was compelled to return to the lands of the disbelievers out of dire necessity, there is no harm; this is a dire necessity. However, if it is not a dire necessity, he should not return. The one who becomes Arabized after emigration commits a major sin. Yes. The one who returns to the desert after he has settled in the land of emigration and learned the rulings of his religion—the desert is harsh and difficult—and the lands of the disbelievers are more severe than the desert. Yes, so he should not return to reside there. But he may go and come back: he may go for trade, for medical treatment, or to visit a relative, and then return. There is no harm in that. Yes.
