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

(1301) Moses said: Lo! I seek refuge in my Lord and your Lord from every scorner who believeth not in a Day of Reckoning.

(1302) And a believing man of Pharaoh's family, who hid his faith, said: Would ye kill a man because he saith: My Lord is Allah, and hath brought you clear proofs from your Lord? If he is lying, then his lie is upon him; and if he is truthful, then some of that wherewith he threateneth you will strike you. Lo! Allah guideth not one who is a prodigal, a liar.

(1303) And verily Joseph brought you of old clear proofs, yet ye ceased not to be in doubt concerning what he brought you till, when he died, ye said: Allah will not send any messenger after him. Thus Allah deceiveth him who is a prodigal, a doubter.

(1304) They say: Came not your messengers unto you with clear proofs? They say: Yea, verily. They say: Then do ye pray, although the prayer of disbelievers is in vain.

(1305) The day when their excuse availeth not the evil-doers, and theirs is the curse, and theirs the ill abode.

(1306) Assuredly the creation of the heavens and the earth is greater than the creation of mankind; but most of mankind know not.

(1307) And the blind man and the seer are not equal, neither are those who believe and do good works (equal with) the evil-doer. Little do ye reflect!

(1308) Lo! the Hour is surely coming, there is no doubt thereof; yet most of mankind believe not.

(1309) Allah it is Who hath appointed for you night that ye may rest therein, and day for seeing. Lo! Allah is a Lord of bounty for mankind, yet most of mankind give not thanks.

(1310) Hast thou not seen those who wrangle concerning the revelations of Allah, how they are turned away? -
