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

(751) And Allah brought you forth from the wombs of your mothers knowing nothing, and gave you hearing and sight and hearts that haply ye might give thanks.

(752) Have they not seen the birds obedient in mid-air? None holdeth them save Allah. Lo! herein, verily, are portents for a people who believe.

(753) And when those who did wrong behold the doom, it will not be made light for them, nor will they be reprieved.

(754) Fulfil the covenant of Allah when ye have covenanted, and break not your oaths after the asseveration of them, and after ye have made Allah surety over you. Lo! Allah knoweth what ye do.

(755) And be not like unto her who unravelleth the thread, after she hath made it strong, to thin filaments, making your oaths a deceit between you because of a nation being more numerous than (another) nation. Allah only trieth you thereby, and He verily will explain to you on the Day of Resurrection that wherein ye differed.

(756) Make not your oaths a deceit between you, lest a foot should slip after being firmly planted and ye should taste evil forasmuch as ye debarred (men) from the way of Allah, and yours should be an awful doom.

(757) And purchase not a small gain at the price of Allah's covenant. Lo! that which Allah hath is better for you, if ye did but know.

(758) And when We put a revelation in place of (another) revelation, - and Allah knoweth best what He revealeth - they say: Lo! thou art but inventing. Most of them know not.

(759) Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom.

(760) Only they invent falsehood who believe not Allah's revelations, and (only) they are the liars.
