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

(181) It is only the devil who would make (men) fear his partisans. Fear them not; fear Me, if ye are true believers.

(182) Let not their conduct grieve thee, who run easily to disbelief, for lo! they injure Allah not at all. It is Allah's Will to assign them no portion in the Hereafter, and theirs will be an awful doom.

(183) Those who purchase disbelief at the price of faith harm Allah not at all, but theirs will be a painful doom.

(184) And let not those who disbelieve imagine that the rein We give them bodeth good unto their souls. We only give them rein that they may grow in sinfulness. And theirs will be a shameful doom.

(185) It is not (the purpose) of Allah to leave you in your present state till He shall separate the wicked from the good. And it is not (the purpose of) Allah to let you know the Unseen. But Allah chooseth of His messengers whom He will, (to receive knowledge thereof). So believe in Allah and His messengers. If ye believe and ward off (evil), yours will be a vast reward.

(186) And let not those who hoard up that which Allah hath bestowed upon them of His bounty think that it is better for them. Nay, it is worse for them. That which they hoard will be their collar on the Day of Resurrection. Allah's is the heritage of the heavens and the earth, and Allah is Informed of what ye do.

(187) (The same are) those who say: Lo! Allah hath charged us that we believe not in any messenger until he bring us an offering which fire (from heaven) shall devour. Say (unto them, O Muhammad): Messengers came unto you before me with miracles, and with that (very miracle) which ye describe. Why then did ye slay them? (Answer that) if ye are truthful!

(188) And (remember) when Allah laid a charge on those who had received the Scripture (He said): Ye are to expound it to mankind and not to hide it. But they flung it behind their backs and bought thereby a little gain. Verily evil is that which they have gained thereby.

(189) Think not that those who exult in what they have given, and love to be praised for what they have not done - Think not, they are in safety from the doom. A painful doom is theirs.

(190) Such as remember Allah, standing, sitting, and reclining, and consider the creation of the heavens and the earth, (and say): Our Lord! Thou createdst not this in vain. Glory be to Thee! Preserve us from the doom of Fire.
