And if We had made it a non-Arabic Qur'an, 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 that preceded from your Lord, it would have been concluded between them. And indeed they are, concerning the Qur'an, in disquieting doubt.
To him [alone] is attributed knowledge of the Hour. And fruits emerge not from their coverings nor does a female conceive or give birth except with His knowledge. And the Day He will call to them, "Where are My 'partners'?" they will say, "We announce to You that there is [no longer] among us any witness [to that]."
And if We let him taste mercy from Us after an adversity which has touched him, he will surely say, "This is [due] to me, and I do not think the Hour will occur; and [even] if I should be returned to my Lord, indeed, for me there will be with Him the best." But We will surely inform those who disbelieved about what they did, and We will surely make them taste a massive punishment.
We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth. But is it not sufficient concerning your Lord that He is, over all things, a Witness?
