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

(431) Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not).

(432) Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me.

(433) But whenever good befell them, they said: This is ours; and whenever evil smote them they ascribed it to the evil auspices of Moses and those with him. Surely their evil auspice was only with Allah. But most of them knew not.

(434) And they said: Whatever portent thou bringest wherewith to bewitch us, we shall not put faith in thee.

(435) And We brought the Children of Israel across the sea, and they came unto a people who were given up to idols which they had. They said: O Moses! Make for us a god even as they have gods. He said: Lo! ye are a folk who know not.

(436) And when We did appoint for Moses thirty nights (of solitude), and added to them ten, and he completed the whole time appointed by his Lord of forty nights; and Moses said unto his brother, Aaron: Take my place among the people. Do right, and follow not the way of mischief-makers.

(437) And when Moses came to Our appointed tryst and his Lord had spoken unto him, he said: My Lord! Show me (Thy Self), that I may gaze upon Thee. He said: Thou wilt not see Me, but gaze upon the mountain! If it stand still in its place, then thou wilt see Me. And when his Lord revealed (His) glory to the mountain He sent it crashing down. And Moses fell down senseless. And when he woke he said: Glory unto Thee! I turn unto Thee repentant, and I am the first of (true) believers.

(438) I shall turn away from My revelations those who magnify themselves wrongfully in the earth, and if they see each token believe it not, and if they see the way of righteousness choose it nor for (their) way, and if they see the way of error choose if for (their) way. That is because they deny Our revelations and are used to disregard them.

(439) And the folk of Moses, after (he left them), chose a calf (for worship), (made) out of their ornaments, of saffron hue, which gave a lowing sound. Saw they not that it spake not unto them nor guided them to any way? They chose it, and became wrong-doers.

(440) And when Moses returned unto his people, angry and grieved, he said: Evil is that (course) which ye took after I had left you. Would ye hasten on the judgment of your Lord? And he cast down the tablets, and he seized his brother by the head, dragging him toward him. He said: Son of my mother! Lo! the folk did judge me weak and almost killed me. Oh, make not mine enemies to triumph over me and place me not among the evil-doers.
