Had We revealed it as a non-Arabic Quran, they would have certainly argued, “If only its verses were made clear ˹in our language˺. What! A non-Arabic revelation for an Arab audience!” Say, ˹O Prophet,˺ “It is a guide and a healing to the believers. As for those who disbelieve, there is deafness in their ears and blindness to it ˹in their hearts˺. It is as if they are being called from a faraway place.”1
— Dr. Mustafa Khattab, the Clear Quran
And if We had made it a foreign [i.e., non-Arabic] Qur’ān, they would have said, "Why are its verses not explained in detail [in our language]? Is it a foreign [recitation] and an Arab [messenger]?" Say, "It is, for those who believe, a guidance and cure." And those who do not believe - in their ears is deafness, and it is upon them blindness. Those are being called from a distant place.1
