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

(441) We divided them into twelve tribes, nations; and We inspired Moses, when his people asked him for water, saying: Smite with thy staff the rock! And there gushed forth therefrom twelve springs, so that each tribe knew their drinking-place. And we caused the white cloud to overshadow them and sent down for them the manna and the quails (saying): Eat of the good things wherewith we have provided you. They wronged Us not, but they were wont to wrong themselves.

(442) But those of them who did wrong changed the word which had been told them for another saying, and We sent down upon them wrath from heaven for their wrongdoing.

(443) Ask them (O Muhammad) of the township that was by the sea, how they did break the Sabbath, how their big fish came unto them visibly upon their Sabbath day and on a day when they did not keep Sabbath came they not unto them. Thus did We try them for that they were evil-livers.

(444) And a generation hath succeeded them who inherited the scriptures. They grasp the goods of this low life (as the price of evil-doing) and say: It will be forgiven us. And if there came to them (again) the offer of the like, they would accept it (and would sin again). Hath not the covenant of the Scripture been taken on their behalf that they should not speak aught concerning Allah save the truth? And they have studied that which is therein. And the abode of the Hereafter is better, for those who ward off (evil). Have ye then no sense?

(445) And as for those who make (men) keep the Scripture, and establish worship - lo! We squander not the wages of reformers.

(446) And (remember) when thy Lord brought forth from the Children of Adam, from their reins, their seed, and made them testify of themselves, (saying): Am I not your Lord? They said: Yea, verily. We testify. (That was) lest ye should say at the Day of Resurrection: Lo! of this we were unaware;

(447) Already have We urged unto hell many of the jinn and humankind, having hearts wherewith they understand not, and having eyes wherewith they see not, and having ears wherewith they hear not. These are as the cattle - nay, but they are worse! These are the neglectful.

(448) And those who deny Our revelations - step by step We lead them on from whence they know not.

(449) Have they not bethought them (that) there is no madness in their comrade? He is but a plain warner.

(450) Have they not considered the dominion of the heavens and the earth, and what things Allah hath created, and that it may be that their own term draweth nigh? In what fact after this will they believe?
