إِفْك

Appears 7 times in the Quran. (Root: افك)
  1. Surely they who concocted the lie are a party from among you. Do not regard it an evil to you; nay, it is good for you. Every man of them shall have what he has earned of sin; and (as for) him who took upon himself the main part thereof, he shall have a grievous chastisement.

  2. Why did not the believing men and the believing women, when you heard it, think well of their own people, and say: This is an evident falsehood?

  3. And those who disbelieve say: This is nothing but a lie which he has forged, and other people have helped him at it; so indeed they have done injustice and (uttered) a falsehood.

  4. You only worship idols besides Allah and you create a lie surely they whom you serve besides Allah do not control for you any sustenance, therefore seek the sustenance from Allah and serve Him and be grateful to Him; to Him you shall be brought back.

  5. And when Our clear communications are recited to them, they say: This is naught but a man who desires to turn you away from that which your fathers worshipped. And they say: This is naught but a lie that is forged. And those who disbelieve say of the truth when it comes to them: This is only clear enchantment.

  6. A lie-- gods besides Allah-- do you desire?

  7. And those who disbelieve say concerning those who believe: If it had been a good, they would not have gone ahead of us therein. And as they do not seek to be rightly directed thereby, they say: It is an old lie.
