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

(91) "Then will ye truly,- O ye that go wrong, and treat (Truth) as falsehood!-

(92) And have ye made it your livelihood that ye should declare it false?

(93) And if he be of those who treat (Truth) as falsehood, who go wrong,

(94) (Those without) will call out, "Were we not with you?" (The others) will reply, "True! but ye led yourselves into temptation; ye looked forward (to our ruin); ye doubted (Allah's Promise); and (your false) desires deceived you; until there issued the Command of Allah. And the Deceiver deceived you in respect of Allah.

(95) If any men among you divorce their wives by Zihar (calling them mothers), they cannot be their mothers: None can be their mothers except those who gave them birth. And in fact they use words (both) iniquitous and false: but truly Allah is one that blots out (sins), and forgives (again and again).

(96) Turnest thou not thy attention to those who turn (in friendship) to such as have the Wrath of Allah upon them? They are neither of you nor of them, and they swear to falsehood knowingly.

(97) O Prophet! When believing women come to thee to take the oath of fealty to thee, that they will not associate in worship any other thing whatever with Allah, that they will not steal, that they will not commit adultery (or fornication), that they will not kill their children, that they will not utter slander, intentionally forging falsehood, and that they will not disobey thee in any just matter,- then do thou receive their fealty, and pray to Allah for the forgiveness (of their sins): for Allah is Oft-Forgiving, Most Merciful.

(98) Who doth greater wrong than one who invents falsehood against Allah, even as he is being invited to Islam? And Allah guides not those who do wrong.

(99) But those who reject Faith and treat Our Signs as falsehoods, they will be Companions of the Fire, to dwell therein for aye: and evil is that Goal.

(100) Allah sets forth, for an example to the Unbelievers, the wife of Noah and the wife of Lut: they were (respectively) under two of our righteous servants, but they were false to their (husbands), and they profited nothing before Allah on their account, but were told: "Enter ye the Fire along with (others) that enter!"
