The hypocrites fear lest a chapter should be sent down to them telling them plainly of what is in their hearts. Say: Go on mocking, surely Allah will bring forth what you fear.

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.
