The word(s) "not" appears 2535 time(s) in 1947 verse(s) in Quran in Mohsin Khan translation.

(21) And fear a Day (of Judgement) when a person shall not avail another, nor will intercession be accepted from him nor will compensation be taken from him nor will they be helped.

(22) And We shaded you with clouds and sent down on you Al-Manna and the quails, (saying): "Eat of the good lawful things We have provided for you," (but they rebelled). And they did not wrong Us but they wronged themselves.

(23) But those who did wrong changed the word from that which had been told to them for another, so We sent upon the wrong-doers Rijz (a punishment) from the heaven because of their rebelling against Allah's obedience. (Tafsir At-Tabari).

(24) And (remember) when Musa (Moses) asked for water for his people, We said: "Strike the stone with your stick." Then gushed forth therefrom twelve springs. Each (group of) people knew its own place for water. "Eat and drink of that which Allah has provided and do not act corruptly, making mischief on the earth."

(25) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(26) Then after that you turned away. Had it not been for the Grace and Mercy of Allah upon you, indeed you would have been among the losers.

(27) He [Musa (Moses)] said, "He says, 'It is a cow neither trained to till the soil nor water the fields, sound, having no other colour except bright yellow.' " They said, "Now you have brought the truth." So they slaughtered it though they were near to not doing it.

(28) Then, after that, your hearts were hardened and became as stones or even worse in hardness. And indeed, there are stones out of which rivers gush forth, and indeed, there are of them (stones) which split asunder so that water flows from them, and indeed, there are of them (stones) which fall down for fear of Allah. And Allah is not unaware of what you do.

(29) And when they (Jews) meet those who believe (Muslims), they say, "We believe", but when they meet one another in private, they say, "Shall you (Jews) tell them (Muslims) what Allah has revealed to you [Jews, about the description and the qualities of Prophet Muhammad صلى الله عليه وسلم, that which are written in the Taurat (Torah)] , that they (Muslims) may argue with you (Jews) about it before your Lord?" Have you (Jews) then no understanding?

(30) Know they (Jews) not that Allah knows what they conceal and what they reveal?
