Say: Whoever is the enemy of Jibreel-- for surely he revealed it to your heart by Allah's command, verifying that which is before it and guidance and good news for the believers.

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 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.

And they say: Our hearts are under coverings from that to which you call us, and there is a heaviness in our ears, and a veil hangs between us and you, so work, we too are working.
