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

(1121) So We took each one in his sin; of them was he on whom We sent a hurricane, and of them was he who was overtaken by the (Awful) Cry, and of them was he whom We caused the earth to swallow, and of them was he whom We drowned. It was not for Allah to wrong them, but they wronged themselves.

(1122) And argue not with the People of the Scripture unless it be in (a way) that is better, save with such of them as do wrong; and say: We believe in that which hath been revealed unto us and revealed unto you; our Allah and your Allah is One, and unto Him we surrender.

(1123) And thou (O Muhammad) wast not a reader of any scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood.

(1124) And they say: Why are not portents sent down upon him from his Lord? Say: Portents are with Allah only, and I am but a plain warner.

(1125) Is it not enough for them that We have sent down unto thee the Scripture which is read unto them? Lo! herein verily is mercy, and a reminder for folk who believe.

(1126) They bid thee hasten on the doom (of Allah). And if a term had not been appointed, the doom would assuredly have come unto them (ere now). And verily it will come upon them suddenly when they perceive not.

(1127) And how many an animal there is that beareth not its own provision! Allah provideth for it and for you. He is the Hearer, the Knower.

(1128) Have they not seen that We have appointed a sanctuary immune (from violence), while mankind are ravaged all around them? Do they then believe in falsehood and disbelieve in the bounty of Allah?

(1129) Who doeth greater wrong than he who inventeth a lie concerning Allah, or denieth the truth when it cometh unto him? Is not there a home in hell for disbelievers?

(1130) It is a promise of Allah. Allah faileth not His promise, but most of mankind know not.
