Surely Allah is not ashamed to set forth any parable-- (that of) a gnat or any thing above that; then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors,

They are lost indeed who kill their children foolishly without knowledge, and forbid what Allah has given to them forging a lie against Allah; they have indeed gone astray, and they are not the followers of the right course.

And two of camels and two of cows. Say: Has He forbidden the two males or the two females or that which the wombs of the two females contain? Or were you witnesses when Allah enjoined you this? Who, then, is more unjust than he who forges a lie against Allah that he should lead astray men without knowledge? Surely Allah does not guide the unjust people.

It is not (attributable to) Allah that He should lead a people astray after He has guided them; He even makes clear to them what they should guard against; surely Allah knows all things.

Is He then Who watches every soul as to what it earns? And yet they give associates to Allah! Say: Give them a name; nay, do you mean to inform Him of what He does not know in the earth, or (do you affirm this) by an outward saying? Rather, their plans are made to appear fair-seeming to those who disbelieve, and they are kept back from the path; and whom Allah makes err, he shall have no guide.

But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people.

Nay! those who are unjust follow their low desires without any knowledge; so who can guide him whom Allah makes err? And they shall have no helpers.

What! is he whose evil deed is made fairseeming to him so much so that he considers it good? Now surely Allah makes err whom He pleases and guides aright whom He pleases, so let not your soul waste away in grief for them; surely Allah is Cognizant of what they do

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.
