The word(s) "not" appears 2535 time(s) in 1947 verse(s) in Quran in Mohsin Khan translation.

(731) And the disbelievers say: "Why is not a sign sent down to him from his Lord?" You are only a warner, and to every people there is a guide.

(732) For him (each person), there are angels in succession, before and behind him. They guard him by the Command of Allah. Verily! Allah will not change the (good) condition of a people as long as they do not change their state (of goodness) themselves (by committing sins and by being ungrateful and disobedient to Allah). But when Allah wills a people's punishment, there can be no turning back of it, and they will find besides Him no protector.

(733) For Him (Allah, Alone) is the Word of Truth (i.e. none has the right to be worshipped but Allah). And those whom they (polytheists and disbelievers) invoke, answer them no more than one who stretches forth his hand (at the edge of a deep well) for water to reach his mouth, but it reaches him not; and the invocation of the disbelievers is nothing but an error (i.e. of no use).

(734) For those who answered their Lord's Call [believed in the Oneness of Allah and followed His Messenger Muhammad صلى الله عليه و سلم i.e. Islamic Monotheism] is Al-Husna (i.e. Paradise). But those who answered not His Call (disbelieved in the Oneness of Allah and followed not His Messenger Muhammad صلى الله عليه و سلم), if they had all that is in the earth together with its like, they would offer it in order to save themselves (from the torment, but it will be in vain). For them there will be the terrible reckoning. Their dwelling-place will be Hell; and worst indeed is that place for rest.

(735) Those who fulfil the Covenant of Allah and break not the Mithaq (bond, treaty, covenant).

(736) And those who join that which Allah has commanded to be joined (i.e. they are good to their relatives and do not sever the bond of kinship), and fear their Lord, and dread the terrible reckoning (i.e. abstain from all kinds of sins and evil deeds which Allah has forbidden and perform all kinds of good deeds which Allah has ordained).

(737) And those who break the Covenant of Allah, after its ratification, and sever that which Allah has commanded to be joined (i.e. they sever the bond of kinship and are not good to their relatives), and work mischief in the land, on them is the curse (i.e. they will be far away from Allah's Mercy), and for them is the unhappy (evil) home (i.e. Hell) .

(738) And those who disbelieved say: "Why is not a sign sent down to him (Muhammad صلى الله عليه و سلم) from his Lord?" Say: "Verily, Allah sends astray whom He wills and guides unto Himself those who turn to Him in repentance."

(739) Those who believed (in the Oneness of Allah - Islamic Monotheism), and whose hearts find rest in the remembrance of Allah: verily, in the remembrance of Allah do hearts find rest .

(740) Those who believed (in the Oneness of Allah - Islamic Monotheism), and work righteousness, Tuba (all kinds of happiness or name of a tree in Paradise) is for them and a beautiful place of (final) return.
