So given that the Muslim countries vary, as do the kaafir countries, and given that the Muslim cannot go to a Muslim state and settle there because of visa and strict settlement laws etc, and that a Muslim may not be able to practice his religion in some Muslim countries, when he may be able to do so in whole or at least in part in some kaafir countries – for all these reasons it is impossible to issue a general ruling that will cover all countries and all individuals. Rather we should say that each Muslim has his own unique set of circumstances and his own ruling that applies to him, and each person is accountable for himself. If he is able to practise his religion in the Muslim country in which he lives more than he can in a kaafir country, then it is not permissible for him to settle in a kaafir country. But if it is the other way round, then it is permissible for him to settle in a kaafir country, subject to the condition that he is confident that he can resist the desires and temptations to be found there by taking the precautionary measures prescribed in sharee’ah.
