The word(s) "false" appears 113 time(s) in 107 verse(s) in Quran in Mohsin Khan translation.

(81) Those who avoid At-Taghut (false deities) by not worshipping them and turn to Allah (in repentance), for them are glad tidings; so announce the good news to My slaves -

(82) And when Allah Alone is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust (from the Oneness of Allah توحيد الله) and when those (whom they obey or worship) besides Him [like all false deities other than Allah, - it may be a Messenger, an angel, a pious man, a jinni, or any other creature even idols, graves of religious people, saints, priests, monks and others.] are mentioned, behold, they rejoice!

(83) The people of Nuh (Noah) and the Confederates after them denied (their Messengers) before these; and every (disbelieving) nation plotted against their Messenger to seize him, and disputed by means of falsehood to refute therewith the truth. So I seized them (with punishment), and how (terrible) was My punishment!

(84) See you not those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah? How are they turning away [from the truth, (i.e. Islamic Monotheism to the falsehood (i.e. polytheism)]?

(85) Those who deny the Book (this Qur'an), and that with which We sent Our Messengers (i.e. to worship none but Allah Alone sincerely, and to reject all false deities and to confess resurrection after the death for recompense) they will come to know (when they will be cast into the Fire of Hell).

(86) And, indeed We have sent Messengers before you (O Muhammad صلى الله عليه وسلم): of some of them We have related to you their story. And of some We have not related to you their story, and it was not given to any Messenger that he should bring a sign except by the Leave of Allah. But, when comes the Commandment of Allah, the matter will be decided with truth, and the followers of falsehood will then be lost.

(87) falsehood cannot come to it from before it or behind it: (it is) sent down by the All-Wise, Worthy of all praise (Allah عز وجل).

(88) And as for those who take as Auliya' (guardians, supporters, helpers, lords, gods, protectors) others besides Him [i.e. they take false deities other than Allah as protectors, and they worship them] - Allah is Hafiz (Protector, Watcher) over them (i.e. takes care of their deeds and will recompense them), and you (O Muhammad صلى الله عليه و سلم) are not a Wakil (guardian or a disposer of their affairs) over them (to protect their deeds).

(89) Or have they partners with Allah (false gods) who have instituted for them a religion which Allah has not ordained? And had it not been for a decisive Word (gone forth already), the matter would have been judged between them. And verily, for the Zalimun (polytheists and wrong-doers) there is a painful torment.

(90) Or say they: "He has invented a lie against Allah?" If Allah willed, He could have sealed up your heart (so that you forget all that you know of the Qur'an). And Allah wipes out falsehood, and establishes the truth (Islam) by His Word (this Qur'an). Verily, He knows well what (secrets) are in the breasts (of mankind).
