Appears 6 times in the Quran. (Root: ضلل)
  1. And two of camels and two of cows. Say: Has He forbidden the two males or the two females or that which the wombs of the two females contain? Or were you witnesses when Allah enjoined you this? Who, then, is more unjust than he who forges a lie against Allah that he should lead astray men without knowledge? Surely Allah does not guide the unjust people.

  2. It is not (attributable to) Allah that He should lead a people astray after He has guided them; He even makes clear to them what they should guard against; surely Allah knows all things.

  3. Turning away haughtily that he may lead (others) astray from the way of Allah; for him is disgrace in this world, and on the day of resurrection We will make him taste the punishment of burning:

  4. And of men is he who takes instead frivolous discourse to lead astray from Allah's path without knowledge, and to take it for a mockery; these shall have an abasing chastisement.

  5. And when distress afflicts a man he calls upon his Lord turning to Him frequently; then when He makes him possess a favor from Him, he forgets that for which he called upon Him before, and sets up rivals to Allah that he may cause (men) to stray off from His path. Say: Enjoy yourself in your ungratefulness a little, surely you are of the inmates of the fire.

  6. So when you meet in battle those who disbelieve, then smite the necks until when you have overcome them, then make (them) prisoners, and afterwards either set them free as a favor or let them ransom (themselves) until the war terminates. That (shall be so); and if Allah had pleased He would certainly have exacted what is due from them, but that He may try some of you by means of others; and (as for) those who are slain in the way of Allah, He will by no means allow their deeds to perish.
