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,

And do not believe but in him who follows your religion. Say: Surely the (true) guidance is the guidance of Allah-- that one may be given (by Him) the like of what you were given; or they would contend with you by an argument before your Lord. Say: Surely grace is in the hand of Allah, He gives it to whom He pleases; and Allah is Ample-giving, Knowing.

Say: Shall we call on that besides Allah, which does not benefit us nor harm us, and shall we be returned back on our heels after Allah has guided us, like him whom the Shaitans have made to fall down perplexed in the earth? He has companions who call him to the right way, (saying): Come to us. Say: Surely the guidance of Allah, that is the (true) guidance, and we are commanded that we should submit to the Lord of the worlds.

And his people disputed with him. He said: Do you dispute with me respecting Allah? And He has guided me indeed; and I do not fear in any way those that you set up with Him, unless my Lord pleases; my Lord comprehends all things in His knowledge; will you not then mind?

Surely your Lord-- He best knows who goes astray from His way, and He best knows those who follow the right course.

Call to the way of your Lord with wisdom and goodly exhortation, and have disputations with them in the best manner; surely your Lord best knows those who go astray from His path, and He knows best those who follow the right way.

Say: Every one acts according to his manner; but your Lord best knows who is best guided in the path.

And that those who have been given the knowledge may know that it is the truth from your Lord, so they may believe in it and their hearts may be lowly before it; and most surely Allah is the Guide of those who believe into a right path.

And Musa said: My Lord knows best who comes with guidance from Him, and whose shall be the good end of the abode; surely the unjust shall not be successful.

Most surely He Who has made the Quran binding on you will bring you back to the destination. Say: My Lord knows best him who has brought the guidance and him who is in manifest error.

And those to whom the knowledge has been given see that which has been revealed to you from your Lord, that is the truth, and it guides into the path of the Mighty, the Praised.

That is their goal of knowledge; surely your Lord knows best him who goes astray from His path and He knows best him who follows the right direction.

Surely your Lord best knows him who errs from His way, and He best knows the followers of the right course.

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.
