The word(s) "not" appears 2535 time(s) in 1947 verse(s) in Quran in Mohsin Khan translation.

(1621) 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!

(1622) And indeed We have destroyed towns (populations) round about you, and We have (repeatedly) shown (them) the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in various ways that they might return (to the truth and believe in the Oneness of Allah - Islamic Monotheism).

(1623) Then why did those whom they had taken for alihah (gods) besides Allah, as a way of approach (to Allah) not help them? Nay, but they vanished completely from them (when there came the torment). And that was their lie, and their inventions which they had been inventing (before their destruction).

(1624) And whosoever does not respond to Allah's Caller, he cannot escape on earth, and there will be no Auliya' (lords, helpers, supporters, protectors) for him besides Allah (from Allah's punishment). Those are in manifest error.

(1625) Do they not see that Allah, Who created the heavens and the earth, and was not wearied by their creation, is Able to give life to the dead? Yes, He surely is Able to do all things.

(1626) And on the Day when those who disbelieve will be exposed to the Fire (it will be said to them): "Is this not the truth?" They will say: "Yes, By our Lord!" He will say: "Then taste the torment, because you used to disbelieve!"

(1627) Therefore be patient (O Muhammad صلى الله عليه وسلم) as did the Messengers of strong will and be in no haste about them (disbelievers). On the Day when they will see that (torment) with which they are promised (i.e. threatened, it will be) as if they had not stayed more than an hour in a single day. (O mankind! this Qur'an is sufficient as) a clear Message (or proclamation to save yourself from destruction). But shall any be destroyed except the people who are Al-Fasiqun (the rebellious against Allah's Command, the disobedient to Allah)?

(1628) Those who disbelieve (in the Oneness of Allah, and in the Message of Prophet Muhammad صلى الله عليه وسلم), and hinder (men) from the Path of Allah (Islamic Monotheism), He will render their deeds vain.

(1629) But those who disbelieve (in the Oneness of Allah - Islamic Monotheism), for them is destruction, and (Allah) will make their deeds vain.

(1630) Have they not travelled through the earth, and seen what was the end of those before them? Allah destroyed them completely, and a similar (fate awaits) the disbelievers.
