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

(411) And We remove whatever rancour may be in their hearts. Rivers flow beneath them. And they say: The praise to Allah, Who hath guided us to this. We could not truly have been led aright if Allah had not guided us. Verily the messengers of our Lord did bring the Truth. And it is cried unto them: This is the Garden. Ye inherit it for what ye used to do.

(412) Between them is a veil. And on the Heights are men who know them all by their marks. And they call unto the dwellers of the Garden: Peace be unto you! They enter it not although they hope (to enter).

(413) And when their eyes are turned toward the dwellers of the Fire, they say: Our Lord! Place us not with the wrong-doing folk.

(414) Are these they of whom ye swore that Allah would not show them mercy? (Unto them it hath been said): Enter the Garden. No fear shall come upon you nor is it ye who will grieve.

(415) (O mankind!) Call upon your Lord humbly and in secret. Lo! He loveth not aggressors.

(416) Work not confusion in the earth after the fair ordering (thereof). and call on Him in fear and hope. Lo! the mercy of Allah is nigh unto the good.

(417) I convey unto you the messages of my Lord and give good counsel unto you, and know from Allah that which ye know not.

(418) And unto (the tribe of) A'ad (We sent) their brother, Hud. He said: O my people! Serve Allah. Ye have no other Allah save Him. Will ye not ward off (evil)?

(419) And We saved him and those with him by a mercy from Us, and We cut the root of those who denied Our revelations and were not believers.

(420) And to (the tribe of) Thamud (We sent) their brother Salih. He said: O my people! Serve Allah. Ye have no other Allah save Him. A wonder from your Lord hath come unto you. Lo! this is the camel of Allah, a token unto you; so let her feed in Allah's earth, and touch her not with hurt lest painful torment seize you.
