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

(1261) not one of them but did deny the messengers, therefor My doom was justified,

(1262) How they burst in upon David, and he was afraid of them. They said: Be not afraid! (We are) two litigants, one of whom hath wronged the other, therefor judge aright between us; be not unjust; and show us the fair way.

(1263) (David) said: He hath wronged thee in demanding thine ewe in addition to his ewes, and lo! many partners oppress one another, save such as believe and do good works, and they are few. And David guessed that We had tried him, and he sought forgiveness of his Lord, and he bowed himself and fell down prostrate and repented.

(1264) (And it was said unto him): O David! Lo! We have set thee as a viceroy in the earth; therefor judge aright between mankind, and follow not desire that it beguile thee from the way of Allah. Lo! those who wander from the way of Allah have an awful doom, forasmuch as they forgot the Day of Reckoning.

(1265) And We created not the heaven and the earth and all that is between them in vain. That is the opinion of those who disbelieve. And woe unto those who disbelieve, from the Fire!

(1266) He said: My Lord! Forgive me and bestow on me sovereignty such as shall not belong to any after me. Lo! Thou art the Bestower.

(1267) And (it was said unto him): Take in thine hand a branch and smite therewith, and break not thine oath. Lo! We found him steadfast, how excellent a slave! Lo! he was ever turning in repentance (to his Lord).

(1268) And they say: What aileth us that we behold not men whom we were wont to count among the wicked?

(1269) Surely pure religion is for Allah only. And those who choose protecting friends beside Him (say): We worship them only that they may bring us near unto Allah. Lo! Allah will judge between them concerning that wherein they differ. Lo! Allah guideth not him who is a liar, an ingrate.

(1270) He hath created the heavens and the earth with truth. He maketh night to succeed day, and He maketh day to succeed night, and He constraineth the sun and the moon to give service, each running on for an appointed term. Is not He the Mighty, the Forgiver?
