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

(451) They ask thee of the (destined) Hour, when will it come to port. Say: Knowledge thereof is with my Lord only. He alone will manifest it at its proper time. It is heavy in the heavens and the earth. It cometh not to you save unawares. They question thee as if thou couldst be well informed thereof. Say: Knowledge thereof is with Allah only, but most of mankind know not.

(452) Say: For myself I have no power to benefit, nor power to hurt, save that which Allah willeth. Had I knowledge of the Unseen, I should have abundance of wealth, and adversity would not touch me. I am but a warner, and a bearer of good tidings unto folk who believe.

(453) He it is Who did create you from a single soul, and therefrom did make his mate that he might take rest in her. And when he covered her she bore a light burden, and she passed (unnoticed) with it, but when it became heavy they cried unto Allah, their Lord, saying: If thou givest unto us aright we shall be of the thankful.

(454) And cannot give them help, nor can they help themselves?

(455) And if ye call them to the Guidance, they follow you not. Whether ye call them or are silent is all one for you.

(456) Have they feet wherewith they walk, or have they hands wherewith they hold, or have they eyes wherewith they see, or have they ears wherewith they hear? Say: Call upon your (so-called) partners (of Allah), and then contrive against me, spare me not!

(457) And if ye (Muslims) call them to the guidance they hear not; and thou (Muhammad) seest them looking toward thee, but they see not.

(458) Their brethren plunge them further into error and cease not.

(459) And when thou bringest not a verse for them they say: Why hast thou not chosen it? Say: I follow only that which is inspired in me from my Lord. This (Qur'an) is insight from your Lord, and a guidance and a mercy for a people that believe.

(460) And do thou (O Muhammad) remember thy Lord within thyself humbly and with awe, below thy breath, at morn and evening. And be not thou of the neglectful.
