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

(811) I made them not to witness the creation of the heavens and the earth, nor their own creation; nor choose I misleaders for (My) helpers.

(812) And (be mindful of) the Day when He will say: Call those partners of Mine whom ye pretended. Then they will cry unto them, but they will not hear their prayer, and We shall set a gulf of doom between them.

(813) We send not the messengers save as bearers of good news and warners. Those who disbelieve contend with falsehood in order to refute the Truth thereby. And they take Our revelations and that wherewith they are threatened as a jest.

(814) And who doth greater wrong than he who hath been reminded of the revelations of his Lord, yet turneth away from them and forgetteth what his hands send forward (to the Judgment)? Lo! on their hearts We have placed coverings so that they understand not, and in their ears a deafness. And though thou call them to the guidance, in that case they can never be led aright.

(815) And when Moses said unto his servant: I will not give up until I reach the point where the two rivers meet, though I march on for ages.

(816) He said: Lo! thou canst not bear with me.

(817) How canst thou bear with that whereof thou canst not compass any knowledge?

(818) He said: Allah willing, thou shalt find me patient and I shall not in aught gainsay thee.

(819) He said: Well, if thou go with me, ask me not concerning aught till I myself make mention of it unto thee.

(820) He said: Did I not tell thee that thou couldst not bear with me?
