The word(s) "falsehood" appears 21 time(s) in 20 verse(s) in Quran in Muhammad Pickthal translation.

(11) We send not the messengers save as bearers of good news and warners. Those who disbelieve contend with falsehood in order to refute the Truth thereby. And they take Our revelations and that wherewith they are threatened as a jest.

(12) And thou (O Muhammad) wast not a reader of any scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood.

(13) Have they not seen that We have appointed a sanctuary immune (from violence), while mankind are ravaged all around them? Do they then believe in falsehood and disbelieve in the bounty of Allah?

(14) Say: The Truth hath come, and falsehood showeth not its face and will not return.

(15) Is it a falsehood - gods beside Allah - that ye desire?

(16) Lo! it is of their falsehood that they say:

(17) (And again of their falsehood): He hath preferred daughters to sons.

(18) falsehood cannot come at it from before it or from behind it. (It is) a revelation from the Wise, the Owner of Praise.

(19) And unto Allah belongeth the Sovereignty of the heavens and the earth; and on the day when the Hour riseth, on that day those who follow falsehood will be lost.

(20) That is because those who disbelieve follow falsehood and because those who believe follow the truth from their Lord. Thus Allah coineth their similitudes for mankind.
