The word(s) "not" appears 1997 time(s) in 1622 verse(s) in Quran in Muhammad Pickthal translation.

(531) It is not for the Prophet, and those who believe, to pray for the forgiveness of idolaters even though they may be near of kin (to them) after it hath become clear that they are people of hell-fire.

(532) It is not for the townsfolk of Al-Madinah and for those around them of the wandering Arabs so stay behind the messenger of Allah and prefer their lives to his life. That is because neither thirst nor toil nor hunger afflicteth them in the way of Allah, nor step they any step that angereth the disbelievers, nor gain they from the enemy a gain, but a good deed is recorded for them therefor. Lo! Allah loseth not the wages of the good.

(533) And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.

(534) See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they heed.

(535) And whenever a surah is revealed, they look one at another (as who should say): Doth anybody see you? Then they turn away. Allah turneth away their hearts because they are a folk who understand not.

(536) Lo! your Lord is Allah Who created the heavens and the earth in six Days, then He established Himself upon the Throne, directing all things. There is no intercessor (with Him) save after His permission. That is Allah, your Lord, so worship Him. Oh, will ye not remind?

(537) He it is Who appointed the sun a splendour and the moon a light, and measured for her stages, that ye might know the number of the years, and the reckoning. Allah created not (all) that save in truth. He detaileth the revelations for people who have knowledge.

(538) Lo! those who expect not the meeting with Us but desire the life of the world and feel secure therein, and those who are neglectful of Our revelations,

(539) If Allah were to hasten on for men the ill (that they have earned) as they would hasten on the good, their respite would already have expired. But We suffer those who look not for the meeting with Us to wander blindly on in their contumacy.

(540) And if misfortune touch a man he crieth unto Us, (while reclining) on his side, or sitting or standing, but when We have relieved him of the misfortune he goeth his way as though he had not cried unto Us because of a misfortune that afflicted him. Thus is what they do made (seeming) fair unto the prodigal.
