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

(661) He said: I will not send him with you till ye give me an undertaking in the name of Allah that ye will bring him back to me, unless ye are surrounded. And when they gave him their undertaking he said: Allah is the Warden over what we say.

(662) And he said: O my sons! Go not in by one gate; go in by different gates. I can naught avail you as against Allah. Lo! the decision rests with Allah only. In Him do I put my trust, and in Him let all the trusting put their trust.

(663) And when they entered in the manner which their father had enjoined, it would have naught availed them as against Allah; it was but a need of Jacob's soul which he thus satisfied; and lo! he was a lord of knowledge because We had taught him; but most of mankind know not.

(664) And when they went in before Joseph, he took his brother unto him, saying: Lo! I, even I, am thy brother, therefore sorrow not for what they did.

(665) They said: By Allah, well ye know we came not to do evil in the land, and are no thieves.

(666) Then he (Joseph) began the search with their bags before his brother's bag, then he produced it from his brother's bag. Thus did We contrive for Joseph. He could not have taken his brother according to the king's law unless Allah willed. We raise by grades (of mercy) whom We will, and over every lord of knowledge there is one more knowing.

(667) They said: If he stealeth, a brother of his stole before. But Joseph kept it secret in his soul and revealed it not unto them. He said (within himself): Ye are in worse case, and Allah knoweth best (the truth of) that which ye allege.

(668) So, When they despaired of (moving) him, they conferred together apart. The eldest of them said: Know ye not how your father took an undertaking from you in Allah's name and how ye failed in the case of Joseph aforetime? Therefore I shall not go forth from the land until my father giveth leave or Allah judgeth for me. He is the Best of Judges.

(669) Return unto your father and say: O our father! Lo! thy son hath stolen. We testify only to that which we know; we are not guardians of the Unseen.

(670) He said: I expose my distress and anguish only unto Allah, and I know from Allah that which ye know not.
