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

(401) They said: Our Lord! We have wronged ourselves. If thou forgive us not and have not mercy on us, surely we are of the lost!

(402) O Children of Adam! Let not Satan seduce you as he caused your (first) parents to go forth from the Garden and tore off from them their robe (of innocence) that he might manifest their shame to them. Lo! he seeth you, he and his tribe, from whence ye see him not. Lo! We have made the devils protecting friends for those who believe not.

(403) And when they do some lewdness they say: We found our fathers doing it and Allah hath enjoined it on us. Say: Allah, verily, enjoineth not lewdness. Tell ye concerning Allah that which ye know not?

(404) A party hath He led aright, while error hath just hold over (another) party, for lo! they choose the devils for protecting supporters instead of Allah and deem that they are rightly guided.

(405) O Children of Adam! Look to your adornment at every place of worship, and eat and drink, but be not prodigal. Lo! He loveth not the prodigals.

(406) Say: My Lord forbiddeth only indecencies, such of them as are apparent and such as are within, and sin and wrongful oppression, and that ye associate with Allah that for which no warrant hath been revealed, and that ye tell concerning Allah that which ye know not.

(407) And every nation hath its term, and when its term cometh, they cannot put it off an hour nor yet advance (it).

(408) He saith: Enter into the Fire among nations of the jinn and humankind who passed away before you. Every time a nation entereth, it curseth its sister (nation) till, when they have all been made to follow one another thither, the last of them saith unto the first of them: Our Lord! These led us astray, so give them double torment of the Fire. He saith: For each one there is double (torment), but ye know not.

(409) Lo! they who deny Our revelations and scorn them, for them the gates of heaven will nor be opened not will they enter the Garden until the camel goeth through the needle's eye. Thus do We requite the guilty.

(410) But (as for) those who believe and do good works - We tax not any soul beyond its scope - Such are rightful owners of the Garden. They abide therein.
