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,

That is because those who disbelieve follow falsehood, and have given them their dowries, taking (them) in marriage, not fornicating nor taking them for paramours in secret; and whoever denies faith, his work indeed is of no account, and in the hereafter he shall be one of the losers.

And by the Lord of the heavens and the earth! it is most surely the truth, just as you do speak.
