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

(191) Our Lord! And give us that which Thou hast promised to us by Thy messengers. Confound us not upon the Day of Resurrection. Lo! Thou breakest not the tryst.

(192) And their Lord hath heard them (and He saith): Lo! I suffer not the work of any worker, male or female, to be lost. Ye proceed one from another. So those who fled and were driven forth from their homes and suffered damage for My cause, and fought and were slain, verily I shall remit their evil deeds from them and verily I shall bring them into Gardens underneath which rivers flow - A reward from Allah. And with Allah is the fairest of rewards.

(193) Let not the vicissitude (of the success) of those who disbelieve, in the land, deceive thee (O Muhammad).

(194) And lo! of the People of the Scripture there are some who believe in Allah and that which is revealed unto you and that which was revealed unto them, humbling themselves before Allah. They purchase not a trifling gain at the price of the revelations of Allah. Verily their reward is with their Lord. Lo! Allah is swift to take account.

(195) O mankind! Be careful of your duty to your Lord Who created you from a single soul and from it created its mate and from them twain hath spread abroad a multitude of men and women. Be careful of your duty toward Allah in Whom ye claim (your rights) of one another, and toward the wombs (that bare you). Lo! Allah hath been a watcher over you.

(196) Give unto orphans their wealth. Exchange not the good for the bad (in your management thereof) nor absorb their wealth into your own wealth. Lo! that would be a great sin.

(197) And if ye fear that ye will not deal fairly by the orphans, marry of the women, who seem good to you, two or three or four; and if ye fear that ye cannot do justice (to so many) then one (only) or (the captives) that your right hands possess. Thus it is more likely that ye will not do injustice.

(198) Give not unto the foolish (what is in) your (keeping of their) wealth, which Allah hath given you to maintain; but feed and clothe them from it, and speak kindly unto them.

(199) Prove orphans till they reach the marriageable age; then, if ye find them of sound judgment, deliver over unto them their fortune; and devour it not by squandering and in haste lest they should grow up Whoso (of the guardians) is rich, let him abstain generously (from taking of the property of orphans); and whoso is poor let him take thereof in reason (for his guardianship). And when ye deliver up their fortune unto orphans, have (the transaction) witnessed in their presence. Allah sufficeth as a Reckoner.

(200) Allah chargeth you concerning (the provision for) your children: to the male the equivalent of the portion of two females, and if there be women more than two, then theirs is two-thirds of the inheritance, and if there be one (only) then the half. And to each of his parents a sixth of the inheritance, if he have a son; and if he have no son and his parents are his heirs, then to his mother appertaineth the third; and if he have brethren, then to his mother appertaineth the sixth, after any legacy he may have bequeathed, or debt (hath been paid). Your parents and your children: Ye know not which of them is nearer unto you in usefulness. It is an injunction from Allah. Lo! Allah is Knower, Wise.
