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

(1791) Allah sets forth an example for those who disbelieve: the wife of Nuh (Noah) and the wife of Lut (Lot). They were under two of our righteous slaves, but they both betrayed them (their husbands by rejecting their doctrine). So they [Nuh (Noah) and Lut (Lot) عليهما السلام] availed them (their respective wives) not against Allah and it was said: "Enter the Fire along with those who enter!"

(1792) Who has created the seven heavens one above another; you can see no fault in the creation of the Most Gracious. Then look again: "Can you see any rifts?"

(1793) And they will say: "Had we but listened or used our intelligence, we would not have been among the dwellers of the blazing Fire!"

(1794) Verily,, those who fear their Lord unseen (i.e. they do not see Him, nor His punishment in the Hereafter), theirs will be forgiveness and a great reward (i.e. Paradise).

(1795) Should not He Who has created know? And He is the Most Kind and Courteous (to His slaves), All-Aware (of everything).

(1796) Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, and then it should quake?

(1797) Or do you feel secure that He, Who is over the heaven (Allah), will not send against you a violent whirlwind? Then you shall know how (terrible) has been My Warning.

(1798) Do they not see the birds above them, spreading out their wings and folding them in? None upholds them except the Most Gracious (Allah). Verily, He is the All-Seer of everything.

(1799) Who is he besides the Most Gracious that can be an army to you to help you? The disbelievers are in nothing but delusion.

(1800) Is he who walks prone (without seeing) on his face, more rightly guided, or he who (sees and) walks upright on the Straight Way (i.e. Islamic Monotheism)?
