And thus We have made you a medium (just) nation that you may be the bearers of witness to the people and (that) the Messenger may be a bearer of witness to you; and We did not make that which you would have to be the qiblah but that We might distinguish him who follows the Messenger from him who turns back upon his heels, and this was surely hard except for those whom Allah has guided aright; and Allah was not going to make your faith to be fruitless; most surely Allah is Affectionate, Merciful to the people.

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.

Allah has not made for any man two hearts within him; nor has He made your wives whose backs you liken to the backs of your mothers as your mothers, nor has He made those whom you assert to be your sons your real sons; these are the words of your mouths; and Allah speaks the truth and He guides to the way.

Have you then considered him who takes his low desire for his god, and Allah has made him err having knowledge and has set a seal upon his ear and his heart and put a covering upon his eye. Who can then guide him after Allah? Will you not then be mindful?

And We have not made the wardens of the fire others than angels, and We have not made their number but as a trial for those who disbelieve, that those who have been given the book may be certain and those who believe may increase in faith, and those who have been given the book and the believers may not doubt, and that those in whose hearts is a disease and the unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.
