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 they do not assign to Allah the attributes due to Him when they say: Allah has not revealed anything to a mortal. Say: Who revealed the Book which Musa brought, a light and a guidance to men, which you make into scattered writings which you show while you conceal much? And you were taught what you did not know, (neither) you nor your fathers. Say: Allah then leave them sporting in their vain discourses.

And We will remove whatever of ill-feeling is in their breasts; the rivers shall flow beneath them and they shall say: All praise is due to Allah Who guided us to this, and we would not have found the way had it not been that Allah had guided us; certainly the messengers of our Lord brought the truth; and it shall be cried out to them that this is the garden of which you are made heirs for what you did.

Say: Is there any of your associates who guides to the truth? Say: Allah guides to the truth. Is He then Who guides to the truth more worthy to be followed, or he who himself does not go aright unless he is guided? What then is the matter with you; how do you judge?

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.
