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

(781) This is (part) of that wisdom wherewith thy Lord hath inspired thee (O Muhammad). And set not up with Allah any other god, lest thou be cast into hell, reproved, abandoned.

(782) The seven heavens and the earth and all that is therein praise Him, and there is not a thing but hymneth His praise; but ye understand not their praise. Lo! He is ever Clement, Forgiving.

(783) And when thou recitest the Qur'an we place between thee and those who believe not in the Hereafter a hidden barrier;

(784) See what similitudes they coin for thee, and thus are all astray, and cannot find a road!

(785) Your Lord is Best Aware of you. If He will, He will have mercy on you, or if He will, He will punish you. We have not sent thee (O Muhammad) as a warden over them.

(786) There is not a township but We shall destroy it ere the Day of Resurrection, or punish it with dire punishment. That is set forth in the Book (of Our decrees).

(787) Feel ye then secure that He will not cause a slope of the land to engulf you, or send a sand-storm upon you, and then ye will find that ye have no protector?

(788) Or feel ye secure that He will not return you to that (plight) a second time, and send against you a hurricane of wind and drown you for your thanklessness, and then ye will not find therein that ye have any avenger against Us?

(789) On the day when We shall summon all men with their record, whoso is given his book in his right hand - such will read their book and they will not be wronged a shred.

(790) And if We had not made thee wholly firm thou mightest almost have inclined unto them a little.
