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.

And there are those of them who seek to listen to you, until when they go forth from you, they say to those who have been given the knowledge: What was it that he said just now? These are they upon whose hearts Allah has set a seal and they follow their low desires.
