The word(s) "false" appears 115 time(s) in 106 verse(s) in Quran in Abdullah Yusuf Ali translation.

(81) No falsehood can approach it from before or behind it: It is sent down by One Full of Wisdom, Worthy of all Praise.

(82) What! Do they say, "He has forged a falsehood against Allah"? But if Allah willed, He could seal up thy heart. And Allah blots out Vanity, and proves the Truth by His Words. For He knows well the secrets of all hearts.

(83) Woe to each sinful dealer in falsehoods:

(84) To Allah belongs the dominion of the heavens and the earth, and the Day that the Hour of Judgment is established,- that Day will the dealers in falsehood perish!

(85) The Unbelievers say of those who believe: "If (this Message) were a good thing, (such men) would not have gone to it first, before us!" And seeing that they guide not themselves thereby, they will say, "this is an (old,) falsehood!"

(86) Why then was no help forthcoming to them from those whom they worshipped as gods, besides Allah, as a means of access (to Allah)? Nay, they left them in the lurch: but that was their falsehood and their invention.

(87) Those who turn back as apostates after Guidance was clearly shown to them,- the Evil One has instigated them and busied them up with false hopes.

(88) Woe to the falsehood-mongers,-

(89) Then woe that Day to those that treat (Truth) as falsehood;-

(90) Then will no (soul) entertain falsehood concerning its coming.
