The word(s) "not" appears 1837 time(s) in 1517 verse(s) in Quran in Abdullah Yusuf Ali translation.

(791) To Him belong all (creatures) in the heavens and on earth: Even those who are in His (very) Presence are not too proud to serve Him, nor are they (ever) weary (of His service):

(792) He cannot be questioned for His acts, but they will be questioned (for theirs).

(793) Or have they taken for worship (other) gods besides him? Say, "Bring your convincing proof: this is the Message of those with me and the Message of those before me." But most of them know not the Truth, and so turn away.

(794) not a messenger did We send before thee without this inspiration sent by Us to him: that there is no god but I; therefore worship and serve Me.

(795) They speak not before He speaks, and they act (in all things) by His Command.

(796) Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?

(797) We granted not to any man before thee permanent life (here): if then thou shouldst die, would they live permanently?

(798) When the Unbelievers see thee, they treat thee not except with ridicule. "Is this," (they say), "the one who talks of your gods?" and they blaspheme at the mention of (Allah) Most Gracious!

(799) Man is a creature of haste: soon (enough) will I show you My Signs; then ye will not ask Me to hasten them!

(800) If only the Unbelievers knew (the time) when they will not be able to ward off the fire from their faces, nor yet from their backs, and (when) no help can reach them!
