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

(501) And (remember) when Shaitan (Satan) made their (evil) deeds seem fair to them and said, "No one of mankind can overcome you this Day (of the battle of Badr) and verily, I am your neighbour (for each and every help)." But when the two forces came in sight of each other, he ran away and said "Verily, I have nothing to do with you. Verily! I see what you see not. Verily! I fear Allah for Allah is Severe in punishment."

(502) "This is because of that which your hands had forwarded. And verily, Allah is not unjust to His slaves."

(503) Verily, The worst of moving (living) creatures before Allah are those who disbelieve , - so they shall not believe.

(504) They are those with whom you made a covenant, but they break their covenant every time and they do not fear Allah.

(505) If you (O Muhammad صلى الله عليه وسلم) fear treachery from any people throw back (their covenant) to them (so as to be) on equal terms (that there will be no more covenant between you and them). Certainly Allah likes not the treacherous.

(506) And let not those who disbelieve think that they can outstrip (escape from the punishment). Verily, they will never be able to save themselves (from Allah's Punishment).

(507) And make ready against them all you can of power, including steeds of war (tanks, planes, missiles, artillery) to threaten the enemy of Allah and your enemy, and others besides whom, you may not know but whom Allah does know. And whatever you shall spend in the Cause of Allah shall be repaid unto you, and you shall not be treated unjustly.

(508) And He has united their (i.e. believers') hearts. If you had spent all that is in the earth, you could not have united their hearts, but Allah has united them. Certainly He is All-Mighty, All-Wise.

(509) O Prophet (Muhammad صلى الله عليه وسلم)! Urge the believers to fight. If there are twenty steadfast persons amongst you, they will overcome two hundreds, and if there be a hundred steadfast persons they will overcome a thousand of those who disbelieve, because they (the disbelievers) are people who do not understand.

(510) It is not for a Prophet that he should have prisoners of war (and free them with ransom) until he had made a great slaughter (among his enemies) in the land. You desire the good of this world (i.e. the money of ransom for freeing the captives), but Allah desires (for you) the Hereafter. And Allah is All-Mighty, All-Wise.
