The word(s) "not" appears 1837 time(s) in 1517 verse(s) in Quran in Abdullah Yusuf Ali translation.

(151) Let not those grieve thee who rush headlong into Unbelief: not the least harm will they do to Allah: Allah's plan is that He will give them no portion in the Hereafter, but a severe punishment.

(152) Those who purchase Unbelief at the price of faith,- not the least harm will they do to Allah, but they will have a grievous punishment.

(153) Let not the Unbelievers think that our respite to them is good for themselves: We grant them respite that they may grow in their iniquity: But they will have a shameful punishment.

(154) Allah will not leave the believers in the state in which ye are now, until He separates what is evil from what is good nor will He disclose to you the secrets of the Unseen. But He chooses of His Messengers (For the purpose) whom He pleases. So believe in Allah. And His messengers: And if ye believe and do right, ye have a reward without measure.

(155) And let not those who covetously withhold of the gifts which Allah Hath given them of His Grace, think that it is good for them: Nay, it will be the worse for them: soon shall the things which they covetously withheld be tied to their necks Like a twisted collar, on the Day of Judgment. To Allah belongs the heritage of the heavens and the earth; and Allah is well-acquainted with all that ye do.

(156) They (also) said: "Allah took our promise not to believe in an messenger unless He showed us a sacrifice consumed by Fire (From heaven)." Say: "There came to you messengers before me, with clear Signs and even with what ye ask for: why then did ye slay them, if ye speak the truth?"

(157) And remember Allah took a covenant from the People of the Book, to make it known and clear to mankind, and not to hide it; but they threw it away behind their backs, and purchased with it some miserable gain! And vile was the bargain they made!

(158) Think not that those who exult in what they have brought about, and love to be praised for what they have not done,- think escape the penalty. For them is a penalty Grievous indeed.

(159) Men who celebrate the praises of Allah, standing, sitting, and lying down on their sides, and contemplate the (wonders of) creation in the heavens and the earth, (With the thought): "Our Lord! not for naught Hast Thou created (all) this! Glory to Thee! Give us salvation from the penalty of the Fire.

(160) And their Lord hath accepted of them, and answered them: "Never will I suffer to be lost the work of any of you, be he male or female: Ye are members, one of another: Those who have left their homes, or been driven out therefrom, or suffered harm in My Cause, or fought or been slain,- verily, I will blot out from them their iniquities, and admit them into Gardens with rivers flowing beneath;- A reward from the presence of Allah, and from His presence is the best of rewards."
