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

(1591) And the heavens and the earth wept not for them, nor were they given a respite.

(1592) "There is nothing but our first death, and we shall not be resurrected.

(1593) And We created not the heavens and the earth, and all that is between them, for mere play.

(1594) We created them not except with truth (i.e. to examine and test those who are obedient and those who are disobedient and then reward the obedient ones and punish the disobedient ones), but most of them know not.

(1595) The Day when a Maula (a near relative) cannot avail a Maula (a near relative) in aught, and no help can they receive,

(1596) Who hears the Verses of Allah (being) recited to him, yet persists with pride as if he heard them not. So announce to him a painful torment!

(1597) Say (O Muhammad صلى الله عليه و سلم) to the believers to forgive those who (harm them and) hope not for the Days of Allah (i.e. His Recompense), that He may recompense people, according to what they have earned (i.e. to punish these disbelievers who harm the believers).

(1598) And gave them clear proofs in matters [by revealing to them the Taurat (Torah)]. And they differed not until after the knowledge came to them, through envy among themselves. Verily, Your Lord will judge between them on the Day of Resurrection about that wherein they used to differ.

(1599) Then We have put you (O Muhammad صلى الله عليه و سلم) on a (plain) way of (Our) commandment [like the one which We commanded Our Messengers before you (i.e. legal ways and laws of the Islamic Monotheism)]. So follow you that (Islamic Monotheism and its laws), and follow not the desires of those who know not. (Tafsir At-Tabari).

(1600) Verily, they can avail you nothing against Allah (if He wants to punish you). Verily, the Zalimun (polytheists, wrong-doers) are Auliya' (protectors, helpers) of one another, but Allah is the Wali (Helper, Protector) of the Muttaqun (the pious. See V.2:2).
