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

(381) And We bestowed upon him Ishaq (Isaac) and Ya'qub (Jacob), each of them We guided, and before him, We guided Nuh (Noah), and among his progeny Dawud (David), Sulaiman (Solomon), Ayyub (Job), Yusuf (Joseph), Musa (Moses), and Harun (Aaron). Thus do We reward Al-Muhsinun (the good-doers - see the footnote of V.9: 120).

(382) They are those whom We gave the Book, Al-Hukm (understanding of the religious laws), and Prophethood. But if these disbelieve therein (the Book, Al-Hukm and Prophethood), then, indeed We have entrusted it to a people (such as the Companions of Prophet Muhammad صلى الله عليه وسلم) who are not disbelievers therein.

(383) They (the Jews, Quraish pagans, idolaters) did not estimate Allah with an estimation due to Him when they said: "nothing did Allah send down to any human being (by revelation)." Say (O Muhammad صلى الله عليه وسلم): "Who then sent down the Book which Musa (Moses) brought, a light and a guidance to mankind which you (the Jews) have made into (separate) papersheets, disclosing (some of it) and concealing much. And you (believers in Allah and His Messenger Muhammad صلى الله عليه وسلم) were taught (through the Qur'an) that which neither you nor your fathers knew." Say: "Allah (sent it down)." Then leave them to play in their vain discussions. (Tafsir Al-Qurtubi).

(384) And truly you have come unto Us alone (without wealth, companions or anything else) as We created you the first time. You have left behind you all that which We had bestowed on you. We see not with you your intercessors whom you claimed to be partners with Allah. Now all relations between you and them have been cut off, and all that you used to claim has vanished from you.

(385) Verily, proofs have come to you from your Lord, so whosoever sees, will do so for (the good of) his ownself, and whosoever blinds himself, will do so to his own harm, and I (Muhammad صلى الله عليه وسلم) am not a watcher over you.

(386) Had Allah willed, they would not have taken others besides Him in worship. And We have not made you a watcher over them nor are you a Wakil (disposer of affairs, guardian, trustee) over them.

(387) And insult not those whom they (disbelievers) worship besides Allah, lest they insult Allah wrongfully without knowledge. Thus We have made fair-seeming to each people its own doings; then to their Lord is their return and He shall then inform them of all that they used to do.

(388) And they swear their strongest oaths by Allah, that if there came to them a sign, they would surely believe therein. Say: "Signs are but with Allah and what will make you (Muslims) perceive that (even) if it (the sign) came, they will not believe?"

(389) And even if We had sent down unto them angels, and the dead had spoken unto them, and We had gathered together all things before their very eyes, they would not have believed, unless Allah willed, but most of them behave ignorantly.

(390) And so We have appointed for every Prophet enemies - Shayatin (devils) among mankind and jinn, inspiring one another with adorned speech as a delusion (or by way of deception). If your Lord had so willed, they would not have done it; so leave them alone with their fabrications. (Tafsir Qurtubi)
