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

(1371) Who heareth the revelations of Allah recited unto him, and then continueth in pride as though he heard them not. Give him tidings of a painful doom.

(1372) Tell those who believe to forgive those who hope not for the days of Allah; in order that He may requite folk what they used to earn.

(1373) And gave them plain commandments. And they differed not until after the knowledge came unto them, through rivalry among themselves. Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ.

(1374) And now have We set thee (O Muhammad) on a clear road of (Our) commandment; so follow it, and follow not the whims of those who know not.

(1375) And Allah hath created the heavens and the earth with truth, and that every soul may be repaid what it hath earned. And they will not be wronged.

(1376) Hast thou seen him who maketh his desire his god, and Allah sendeth him astray purposely, and sealeth up his hearing and his heart, and setteth on his sight a covering? Then who will lead him after Allah (hath condemned him)? Will ye not then heed?

(1377) Say (unto them, O Muhammad): Allah giveth life to you, then causeth you to die, then gathereth you unto the Day of Resurrection whereof there is no doubt. But most of mankind know not.

(1378) And as for those who disbelieved (it will be said unto them): Were not Our revelations recited unto you? But ye were scornful and became a guilty folk.

(1379) And when it was said: Lo! Allah's promise is the truth, and there is no doubt of the Hour's coming, ye said: We know not what the Hour is. We deem it naught but a conjecture, and we are by no means convinced.

(1380) This, forasmuch as ye made the revelations of Allah a jest, and the life of the world beguiled you. Therefor this day they come not forth from thence, nor can they make amends.
