The word(s) "not" appears 2417 time(s) in 1904 verse(s) in Quran in Muhammad Habib Shakir translation.

(1521) Most surely the hour is coming, there is no doubt therein, but most people do not believe.

(1522) Allah is He Who made for you the night that you may rest therein and the day to see; most surely Allah is Gracious to men, but most men do not give thanks.

(1523) Have you not seen those who dispute with respect to the communications of Allah: how are they turned away?

(1524) Besides Allah? They shall say: They are gone away from us, nay, we used not to call upon anything before. Thus does Allah confound the unbelievers.

(1525) And certainly We sent apostles before you: there are some of them that We have mentioned to you and there are others whom We have not mentioned to you, and it was not meet for an apostle that he should bring a sign except with Allah's permission, but when the command of Allah came, judgment was given with truth, and those who treated (it) as a lie were lost.

(1526) Have they not then journeyed in the land and seen how was the end of those before them? They were more (in numbers) than these and greater in strength and in fortifications in the land, but what they earned did not avail them.

(1527) But their belief was not going to profit them when they had seen Our punishment; (this is) Allah's law, which has indeed obtained in the matter of His servants, and there the unbelievers are lost.

(1528) A herald of good news and a warner, but most of them turn aside so they hear not.

(1529) (To) those who do not give poor-rate and they are unbelievers in the hereafter.

(1530) When their apostles came to them from before them and from behind them, saying, Serve nothing but Allah, they said: If our Lord had pleased He would certainly have sent down angels, so we are surely unbelievers in that with which you are sent.
