Question: We request you provide us with advice for those who travel out [of Saudi Arabia] to live with a non-Muslim family claiming this will hasten their learning of the English language?
Response: If a Muslim is compelled to travel to a non-Islaamic country, then he must fear Allaah with regards to himself and strive to protect [the practice of] his religion. For indeed his religion is the most precious and most honoured thing, so he must protect his Islaam, and not to cheapen it [when] with them, for indeed honour is in [upholding] the religion. And [so] the Muslim must hold fast to his religion in any place to which he travels, and he must beware of living with those who oppose his religion. So living with the [non-Muslim] family and eating with them, and sleeping under their roof – in all of this there is concern for the Muslim; this may lead him to fall into that which is prohibited and detested, and it may also lead him away from his religion and belief. O Muslim, the religion is more precious than anything, so [be sure to] protect your religion if you are compelled to travel to the land of the disbelievers.
