And of them is he who hearkens to you, and We have cast veils over their hearts lest they understand it and a heaviness into their ears; and even if they see every sign they will not believe in it; so much so that when they come to you they only dispute with you; those who disbelieve say: This is naught but the stories of the ancients.

Say: He has the power that He should send on you a chastisement from above you or from beneath your feet, or that He should throw you into confusion, (making you) of different parties; and make some of you taste the fighting of others. See how We repeat the communications that they may understand.

And He it is Who has brought you into being from a single soul, then there is (for you) a resting-place and a depository; indeed We have made plain the communications for a people who understand.

And who is more unjust than he who is reminded of the communications of his Lord, then he turns away from them and forgets what his two hands have sent before? Surely We have placed veils over their hearts lest they should understand it and a heaviness in their ears; and if you call them to the guidance, they will not ever follow the right course in that case.
