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

(351) Those who believe and obscure not their belief by wrongdoing, theirs is safety; and they are rightly guided.

(352) Those are they unto whom We gave the Scripture and command and prophethood. But if these disbelieve therein, then indeed We shall entrust it to a people who will not be disbelievers therein.

(353) And they measure not the power of Allah its true measure when they say: Allah hath naught revealed unto a human being. Say (unto the Jews who speak thus): Who revealed the Book which Moses brought, a light and guidance for mankind, which ye have put on parchments which ye show, but ye hide much (thereof), and (by which) ye were taught that which ye knew not yourselves nor (did) your fathers (know it)? Say: Allah. Then leave them to their play of cavilling.

(354) Who is guilty of more wrong than he who forgeth a lie against Allah, or saith: I am inspired, when he is not inspired in aught; and who saith: I will reveal the like of that which Allah hath revealed? If thou couldst see, when the wrong-doers reach the pangs of death and the angels stretch their hands out (saying): Deliver up your souls. This day ye are awarded doom of degradation for that ye spake concerning Allah other than the truth, and used to scorn His portents.

(355) Now have ye come unto Us solitary as We did create you at the first, and ye have left behind you all that We bestowed upon you, and We behold not with you those your intercessors, of whom ye claimed that they possessed a share in you. Now is the bond between you severed, and that which ye presumed hath failed you.

(356) Vision comprehendeth Him not, but He comprehendeth (all) vision. He is the Subtile, the Aware.

(357) Proofs have come unto you from your Lord, so whoso seeth, it is for his own good, and whoso is blind is blind to his own hurt. And I am not a keeper over you.

(358) Had Allah willed, they had not been idolatrous. We have not set thee as a keeper over them, nor art thou responsible for them.

(359) Revile not those unto whom they pray beside Allah lest they wrongfully revile Allah through ignorance. Thus unto every nation have We made their deed seem fair. Then unto their Lord is their return, and He will tell them what they used to do.

(360) And they swear a solemn oath by Allah that if there come unto them a portent they will believe therein. Say; Portents are with Allah and (so is) that which telleth you that if such came unto them they would not believe.
