سورة Fussilat ( Explained in Detail ) - الآية 44

Had We made it a non-Arabic Quran, they would have said, ‘Why have not its signs been articulated?’ ‘What! A non-Arabian [scripture] and an Arabian [prophet]!?’ Say, ‘It is guidance and healing for those who have faith. As for those who are faithless, there is a deafness in their ears and it is lost to their sight: [to them it is as if] they were called from a distant place.’
