If We had made it a foreign Quran, they would have said, ‘If only its verses were clear! What? Foreign speech to an Arab?’ Say, ‘It is guidance and healing for those who have faith, but the ears of the disbelievers are heavy, they are blind to it, it is as if they are being called from a distant place.’
And if We had sent this as a Qur’ân 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’ân) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."
