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

(1221) He said: "I intend to wed one of these two daughters of mine to you, on condition that you serve me for eight years; but if you complete ten years, it will be (a favour) from you. But I intend not to place you under a difficulty. If Allah wills, you will find me one of the righteous."

(1222) "And throw your stick!" But when he saw it moving as if it were a snake, he turned in flight, and looked not back. (It was said:) "O Musa (Moses)! Draw near, and fear not. Verily, you are of those who are secure.

(1223) Allah said: "We will strengthen your arm through your brother, and give you both power, so they shall not be able to harm you: with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), you two as well as those who follow you will be the victors."

(1224) Then when Musa (Moses) came to them with Our Clear Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they said: "This is nothing but invented magic. Never did we hear of this among our fathers of old."

(1225) Musa (Moses) said: "My Lord knows best him who came with guidance from Him, and whose will be the happy end in the Hereafter. Verily, the Zalimun (wrong-doers, polytheists and disbelievers in the Oneness of Allah) will not be successful."

(1226) Fir'aun (Pharaoh) said: "O chiefs! I know not that you have an ilah (a god) other than me. So kindle for me (a fire), O Haman, to bake (bricks out of) clay, and set up for me a Sarh (a lofty tower, or palace) in order that I may look at (or look for) the Ilah (God) of Musa (Moses); and verily, I think that he [Musa (Moses)] is one of the liars."

(1227) And We made them leaders inviting to the Fire: and on the Day of Resurrection, they will not be helped.

(1228) And you (O Muhammad صلى الله عليه وسلم) were not on the western side (of the Mount), when We made clear to Musa (Moses) the commandment, and you were not among the witnesses.

(1229) But We created generations [after generations i.e. after Musa (Moses) عليه السلام], and long were the ages that passed over them. And you (O Muhammad صلى الله عليه وسلم) were not a dweller among the people of Madyan (Midian), reciting Our Verses to them. But it is We Who kept sending (Messengers).

(1230) And you (O Muhammad صلى الله عليه وسلم) were not at the side of the Tur (Mount) when We did call: [it is said that Allah called the followers of Muhammad صلى الله عليه وسلم, and they answered His Call, or that Allah called Musa (Moses)]. But (you are sent) as a mercy from your Lord, to give warning to a people to whom no warner had come before you: in order that they may remember or receive admonition. [Tafsir At-Tabari].
