The word(s) "not" appears 2535 time(s) in 1947 verse(s) in Quran in Mohsin Khan translation.

(891) (The young men said to one another): "And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the Cave; your Lord will open a way for you from His Mercy and will make easy for you your affair (i.e. will give you what you will need of provision, dwelling)."

(892) Likewise, We awakened them (from their long deep sleep) that they might question one another. A speaker from among them said: "How long have you stayed (here)?" They said: "We have stayed (perhaps) a day or part of a day." They said: "Your Lord (Alone) knows best how long you have stayed (here). So send one of you with this silver coin of yours to the town, and let him find out which is the good lawful food, and bring some of that to you. And let him be careful and let no man know of you.

(893) (Some) say they were three, the dog being the fourth among them; and (others) say they were five, the dog being the sixth, - guessing at the unseen; (yet others) say they were seven, and the dog being the eighth. Say (O Muhammad صلى الله عليه وسلم): "My Lord knows best their number; none knows them but a few." So debate not (about their number) except with the clear proof (which We have revealed to you). And consult not any of them (people of the Scripture - Jews and Christians) about (the affair of) the people of the Cave.

(894) And keep yourself (O Muhammad صلى الله عليه وسلم) patiently with those who call on their Lord (i.e. your companions who remember their Lord with glorification, praising in prayers, and other righteous deeds) morning and afternoon, seeking His Face; and let not your eyes overlook them, desiring the pomp and glitter of the life of the world; and obey not him whose heart We have made heedless of Our Remembrance, and who follows his own lusts, and whose affair (deeds) has been lost.

(895) Verily as for those who believed and did righteous deeds, certainly We shall not make the reward of anyone who does his (righteous) deeds in the most perfect manner to be lost.

(896) Each of those two gardens brought forth its produce, and failed not in the least therein, and We caused a river to gush forth in the midst of them.

(897) And he went into his garden while in a state (of pride and disbelief) unjust to himself. He said: "I think not that this will ever perish.

(898) "And I think not the Hour will ever come, and if indeed I am brought back to my Lord, (on the Day of Resurrection), I surely shall find better than this when I return to Him."

(899) And (remember) the Day We shall cause the mountains to pass away (like clouds of dust), and you will see the earth as a levelled plain, and we shall gather them all together so as to leave not one of them behind.

(900) I (Allah) made them (Iblis and his offspring) not to witness (nor took their help in) the creation of the heavens and the earth and not (even) their own creation, nor was I (Allah) to take the misleaders as helpers.
