The word(s) "foreign" appears 3 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) They (people of the city) said: "Did we not forbid you from entertaining (or protecting) any of the 'Alamin (people, foreigners and strangers from us)?"

(2) And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad صلى الله عليه و سلم)." The tongue of the man they refer to is foreign, while this (the Qur'an) is a clear Arabic tongue.

(3) And if We had sent this as a Qur'an in a foreign language (other than Arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."
