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

(31) And there are among them (Jews) unlettered people, who know not the Book, but they trust upon false desires and they but guess.

(32) And they (Jews) say, "The Fire (i.e. Hell-fire on the Day of Resurrection) shall not touch us but for a few numbered days." Say (O Muhammad صلى الله عليه وسلم to them): "Have you taken a covenant from Allah, so that Allah will not break His Covenant? Or is it that you say of Allah what you know not?"

(33) And those who believe (in the Oneness of Allah تعالى - Islamic Monotheism) and do righteous good deeds, they are dwellers of Paradise, they will dwell therein forever. (See V. 2:257)

(34) And (remember) when We took your covenant (saying): Shed not the blood of your (people), nor turn out your own people from their dwellings. Then, (this) you ratified and (to this) you bear witness.

(35) After this, it is you who kill one another and drive out a party of you from their homes, assist (their enemies) against them, in sin and transgression. And if they come to you as captives, you ransom them, although their expulsion was forbidden to you. Then do you believe in a part of the Scripture and reject the rest? Then what is the recompense of those who do so among you, except disgrace in the life of this world, and on the Day of Resurrection they shall be consigned to the most grievous torment. And Allah is not unaware of what you do.

(36) Those are they who have bought the life of this world at the price of the Hereafter. Their torment shall not be lightened nor shall they be helped.

(37) And indeed, We gave Musa (Moses) the Book and followed him up with a succession of Messengers. And We gave 'Îsa (Jesus), the son of Maryam (Mary), clear signs and supported him with Ruh-ul-Qudus [Jibrael (Gabriel عليه السلام)]. Is it that whenever there came to you a Messenger with what you yourselves desired not, you grew arrogant? Some you disbelieved and some you killed.

(38) And they say, "Our hearts are wrapped (i.e. do not hear or understand Allah's Word)." Nay, Allah has cursed them for their disbelief, so little is that which they believe.

(39) Say to (them): "If the home of the Hereafter with Allah is indeed for you specially and not for others, of mankind, then long for death if you are truthful."

(40) And verily, you will find them (the Jews) the greediest of mankind for life and (even greedier) than those who ascribe partners to Allah (and do not believe in Resurrection - Majus, pagans, and idolaters). Everyone of them wishes that he could be given a life of a thousand years. But the grant of such life will not save him even a little from (due) punishment. And Allah is All-Seer of what they do.
