The word(s) "false" appears 41 time(s) in 39 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) That is because Allah is the Truth, and that what they call upon besides Him-- that is the falsehood, and because Allah is the High, the Great.

(22) 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?

(23) 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.

(24) And they who do not bear witness to what is false, and when they pass by what is vain, they pass by nobly.

(25) Say: Allah is sufficient as a witness between me and you; He knows what is in the heavens and the earth. And (as for) those who believe in the falsehood and disbelieve in Allah, these it is that are the losers.

(26) Do they not see that We have made a sacred territory secure, while men are carried off by force from around them? Will they still believe in the falsehood and disbelieve in the favour of Allah?

(27) And certainly We have set forth for men every kind of example in this Quran; and if you should bring them a communication, those who disbelieve would certainly say: You are naught but false claimants.

(28) This is because Allah is the Truth, and that which they call upon besides Him is the falsehood, and that Allah is the High, the Great.

(29) And those who speak evil things of the believing men and the believing women without their having earned (it), they are guilty indeed of a false accusation and a manifest sin.

(30) Say: The truth has come, and the falsehood shall vanish and shall not come back.
