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 what reason have you that you should not eat of that on which Allah's name has been mentioned, and He has already made plain to you what He has forbidden to you-- excepting what you are compelled to; and most surely many would lead (people) astray by their low desires out of ignorance; surely your Lord-- He best knows those who exceed the limits.
