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

(1451) If We willed, We verily could make it chaff, then would ye cease not to exclaim:

(1452) If We willed We verily could make it bitter. Why then, give ye not thanks?

(1453) - And We are nearer unto him than ye are, but ye see not -

(1454) Why then, if ye are not in bondage (unto Us),

(1455) Do ye not force it back, if ye are truthful?

(1456) What aileth you that ye believe not in Allah, when the messenger calleth you to believe in your Lord, and He hath already made a covenant with you, if ye are believers?

(1457) And what aileth you that ye spend not in the way of Allah when unto Allah belongeth the inheritance of the heavens and the earth? Those who spent and fought before the victory are not upon a level (with the rest of you). Such are greater in rank than those who spent and fought afterwards. Unto each hath Allah promised good. And Allah is Informed of what ye do.

(1458) They will cry unto them (saying): Were we not with you? They will say: Yea, verily; but ye tempted one another, and hesitated, and doubted, and vain desires beguiled you till the ordinance of Allah came to pass; and the deceiver deceived you concerning Allah;

(1459) Is not the time ripe for the hearts of those who believe to submit to Allah's reminder and to the truth which is revealed, that they become not as those who received the scripture of old but the term was prolonged for them and so their hearts were hardened, and many of them are evil-livers.

(1460) Race one with another for forgiveness from your Lord and a Garden whereof the breadth is as the breadth of the heavens and the earth, which is in store for those who believe in Allah and His messengers. Such is the bounty of Allah, which He bestoweth upon whom He will, and Allah is of Infinite Bounty.
