And We have placed coverings on their hearts and a heaviness in their ears lest they understand it, and when you mention your Lord alone in the Quran they turn their backs in aversion.

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.

And intercession will not avail aught with Him save of him whom He permits. Until when fear shall be removed from their hearts, They shall say: What is it that your Lord said? They shall say: The truth. And He is the Most High, the Great.
