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,

Have you not considered him (Namrud) who disputed with Ibrahim about his Lord, because Allah had given him the kingdom? When Ibrahim said: My Lord is He who gives life and causes to die, he said: I give life and cause death. Ibrahim said: So surely Allah causes the sun to rise from the east, then make it rise from the west; thus he who disbelieved was confounded; and Allah does not guide aright the unjust people.

Have you not seen those to whom a portion of the Book has been given? They believe in idols and false deities and say of those who disbelieve: These are better guided in the path than those who believe.

And those who disbelieve say: Why has not a sign been sent down upon him from his Lord? You are only a warner and (there is) a guide for every people.

And those who disbelieve say: Why is not a sign sent down upon him by his Lord? Say: Surely Allah makes him who will go astray, and guides to Himself those who turn (to Him).

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.

(The warner) said: What! even if I bring to you a better guide than that on which you found your fathers? They said: Surely we are unbelievers in that with which you are sent.

Say: Have you considered if it is from Allah, and you disbelieve in it, and a witness from among the children of Israel has borne witness of one like it, so he believed, while you are big with pride; surely Allah does not guide the unjust people.

And those who disbelieve say concerning those who believe: If it had been a good, they would not have gone ahead of us therein. And as they do not seek to be rightly directed thereby, they say: It is an old lie.

That is because there came to them their messengers with clear arguments, but they said: Shall mortals guide us? So they disbelieved and turned back, and Allah does not stand in need (of anything), and Allah is Self-sufficient, Praised.

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.
