Surah Al-Anaam Ayahs #113 Translated in English

And they swear by Allāh their strongest oaths that if a sign came to them, they would surely believe in it. Say, "The signs are only with [i.e., from] Allāh." And what will make you perceive that even if it [i.e., a sign] came, they would not believe.

And We will turn away their hearts and their eyes just as they refused to believe in it [i.e., the revelation] the first time. And We will leave them in their transgression, wandering blindly.

And even if We had sent down to them the angels [with the message] and the dead spoke to them [of it] and We gathered together every [created] thing in front of them, they would not believe unless Allāh should will. But most of them, [of that], are ignorant.

And thus We have made for every prophet an enemy - devils from mankind and jinn, inspiring to one another decorative speech in delusion. But if your Lord had willed, they would not have done it, so leave them and that which they invent.

And [it is] so the hearts of those who disbelieve in the Hereafter will incline toward it [i.e., deceptive speech] and that they will be satisfied with it and that they will commit that which they are committing.
