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

(421) And remember how He made you viceroys after A'ad and gave you station in the earth. Ye choose castles in the plains and hew the mountains into dwellings. So remember (all) the bounties of Allah and do not evil, making mischief in the earth.

(422) And (Salih) turned from them and said: O my people! I delivered my Lord's message unto you and gave you good advice, but ye love not good advisers.

(423) And the answer of his people was only that they said (one to another): Turn them out of your township. They are folk, forsooth, who keep pure.

(424) And unto Midian (We sent) their brother, Shu'eyb. He said: O my people! Serve Allah. Ye have no other Allah save Him. Lo! a clear proof hath come unto you from your Lord; so give full measure and full weight and wrong not mankind in their goods, and work not confusion in the earth after the fair ordering thereof. That will be better for you, if ye are believers.

(425) Lurk not on every road to threaten (wayfarers), and to turn away from Allah's path him who believeth in Him, and to seek to make it crooked. And remember, when ye were but few, how He did multiply you. And see the nature of the consequence for the corrupters!

(426) And if there is a party of you which believeth in that wherewith I have been sent, and there is a party which believeth not, then have patience until Allah judge between us. He is the Best of all who deal in judgment.

(427) We should have invented a lie against Allah if we returned to your religion after Allah hath rescued us from it. It is not for us to return to it unless Allah our Lord should (so) will. Our Lord comprehendeth all things in knowledge. In Allah do we put our trust. Our Lord! Decide with truth between us and our folk, for Thou art the best of those who make decision.

(428) Those who denied Shu'eyb became as though they had not dwelt there. Those who denied Shu'eyb, they were the losers.

(429) Then changed We the evil plight for good till they grew affluent and said: Tribulation and distress did touch our fathers. Then We seized them unawares, when they perceived not.

(430) Is it not an indication to those who inherit the land after its people (who thus reaped the consequence of evil-doing) that, if We will, We can smite them for their sins and print upon their hearts so that they hear not?
