The word(s) "falsehood" appears 22 time(s) in 21 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) (As for) those of you who put away their wives by likening their backs to the backs of their mothers, they are not their mothers; their mothers are no others than those who gave them birth; and most surely they utter a hateful word and a falsehood and most surely Allah is Pardoning, Forgiving.
