Surah Fussilat Ayahs #45 Translated in English

Indeed, those who disbelieve in the message [i.e., the Qur’ān] after it has come to them... And indeed, it is a mighty Book.

Falsehood cannot approach it from before it or from behind it; [it is] a revelation from a [Lord who is] Wise and Praiseworthy.

Nothing is said to you, [O Muḥammad], except what was already said to the messengers before you. Indeed, your Lord is a possessor of forgiveness and a possessor of painful penalty.

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.

And We had already given Moses the Scripture, but it came under disagreement. And if not for a word [i.e., decree] that preceded from your Lord, it would have been concluded between them. And indeed they are, concerning it [i.e., the Qur’ān], in disquieting doubt.
