The word(s) "deny" appears 99 time(s) in 96 verse(s) in Quran in Mohsin Khan translation.

(41) 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).

(42) And He shows you His Ayat (signs and proofs) (of His Oneness in all the above-mentioned things). Which, then of the Ayat (signs and proofs) of Allah do you deny?

(43) As for 'Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength?" See they not that Allah, Who created them was mightier in strength than them. And they used to deny Our Ayat (proofs, evidence, verses, lessons, revelations, etc.)!

(44) That is the recompense of the enemies of Allah: the Fire. Therein will be for them the eternal home, a (deserving) recompense for that they used to deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(45) Verily, those who turn away from Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc. by attacking, distorting and denying them) are not hidden from Us. Is he who is cast into the Fire better or he who comes secure on the Day of Resurrection? Do what you will. Verily He is All-Seer of what you do (this is a severe threat to the disbelievers ).

(46) Answer the Call of your Lord (i.e. accept the Islamic Monotheism, O mankind, and jinn) before there comes from Allah a Day which cannot be averted (i.e. the Day of Resurrection). You will have no refuge on that Day nor there will be for you any denying (of your crimes as they are all recorded in the Book of your deeds).

(47) Say (O Muhammad صلى الله عليه و سلم): "If the Most Gracious (Allah) had a son (or children as you pretend), then I am the first of Allah's worshippers [who deny and refute this claim of yours (and the first to believe in Allah Alone and testify that He has no children)]." [Tafsir At-Tabari].

(48) And when mankind are gathered (on the Day of Resurrection), they (false deities) will become their enemies and will deny their worshipping.

(49) Say: "Tell me! If this (Qur'an) is from Allah and you deny it, and a witness from among the Children of Israel ('Abdullah bin Salam رضي الله عنه) testifies that [this Qur'an is from Allah (like the Taurat (Torah)], and he believed (embraced Islam) while you are too proud (to believe)." Verily, Allah guides not the people who are Zalimun (polytheists, disbelievers and wrong-doers).

(50) And indeed We had firmly established them with that wherewith We have not established you (O Quraish)! And We had assigned them the (faculties of) hearing (ears), seeing (eyes), and hearts; but their hearing (ears), seeing (eyes), and their hearts availed them nothing since they used to deny the Ayat (Allah's Prophets and their Prophethood, proofs, evidence, verses, signs, revelations) of Allah, and they were completely encircled by that which they used to mock at!
