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

(1411) Allah hath fulfilled the vision for His messenger in very truth. Ye shall indeed enter the Inviolable Place of Worship, if Allah will, secure, (having your hair) shaven and cut, not fearing. But He knoweth that which ye know not, and hath given you a near victory beforehand.

(1412) O ye who believe! Be not forward in the presence of Allah and His messenger, and keep your duty to Allah. Lo! Allah is Hearer, Knower.

(1413) O ye who believe! Lift not up your voices above the voice of the Prophet, nor shout when speaking to him as ye shout one to another, lest your works be rendered vain while ye perceive not.

(1414) O ye who believe! Let not a folk deride a folk who may be better than they (are), not let women (deride) women who may be better than they are; neither defame one another, nor insult one another by nicknames. Bad is the name of lewdness after faith. And whoso turneth not in repentance, such are evil-doers.

(1415) O ye who believe! Shun much suspicion; for lo! some suspicion is a crime. And spy not, neither backbite one another. Would one of you love to eat the flesh of his dead brother? Ye abhor that (so abhor the other)! And keep your duty (to Allah). Lo! Allah is Relenting, Merciful.

(1416) O mankind! Lo! We have created you male and female, and have made you nations and tribes that ye may know one another. Lo! the noblest of you, in the sight of Allah, is the best in conduct. Lo! Allah is Knower, Aware.

(1417) The wandering Arabs say: We believe. Say (unto them, O Muhammad): Ye believe not, but rather say "We submit," for the faith hath not yet entered into your hearts. Yet, if ye obey Allah and His messenger, He will not withhold from you aught of (the reward of) your deeds. Lo! Allah is Forgiving, Merciful.

(1418) The (true) believers are those only who believe in Allah and His messenger and afterward doubt not, but strive with their wealth and their lives for the cause of Allah. Such are the sincere.

(1419) They make it a favour unto thee (Muhammad) that they have surrendered (unto Him). Say: Deem not your Surrender a favour unto me; but Allah doth confer a favour on you, inasmuch as He hath led you to the Faith, if ye are earnest.

(1420) Have they not then observed the sky above them, how We have constructed it and beautified it, and how there are no rifts therein?
