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

(1141) So have patience (O Muhammad)! Allah's promise is the very truth, and let not those who have no certainty make thee impatient.

(1142) And when Our revelations are recited unto him he turneth away in pride as if he heard them not, as if there were a deafness in his ears. So give him tidings of a painful doom.

(1143) He hath created the heavens without supports that ye can see, and hath cast into the earth firm hills, so that it quake not with you; and He hath dispersed therein all kinds of beasts. And We send down water from the sky and We cause (plants) of every goodly kind to grow therein.

(1144) But if they strive with thee to make thee ascribe unto Me as partner that of which thou hast no knowledge, then obey them not. Consort with them in the world kindly, and follow the path of him who repenteth unto Me. Then unto Me will be your return, and I shall tell you what ye used to do -

(1145) Turn not thy cheek in scorn toward folk, nor walk with pertness in the land. Lo! Allah loveth not each braggart boaster.

(1146) See ye not how Allah hath made serviceable unto you whatsoever is in the skies and whatsoever is in the earth and hath loaded you with His favours both without and within? Yet of mankind is he who disputeth concerning Allah, without knowledge or guidance or a scripture giving light.

(1147) And whosoever disbelieveth, let not his disbelief afflict thee (O Muhammad). Unto Us is their return, and We shall tell them what they did. Lo! Allah is Aware of what is in the breasts (of men).

(1148) If thou shouldst ask them: Who created the heavens and the earth? they would answer: Allah. Say: Praise be to Allah! But most of them know not.

(1149) And if all the trees in the earth were pens, and the sea, with seven more seas to help it, (were ink), the words of Allah could not be exhausted. Lo! Allah is Mighty, Wise.

(1150) Hast thou not seen how Allah causeth the night to pass into the day and causeth the day to pass into the night, and hath subdued the sun and the moon (to do their work), each running unto an appointed term; and that Allah is Informed of what ye do?
