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

(1891) Verily, Al-Abrar (the pious believers of Islamic Monotheism) will be in Delight (Paradise).

(1892) And, whenever they passed by them, used to wink one to another (in mockery).

(1893) But they (disbelievers, sinners) had not been sent as watchers over them (the believers).

(1894) Are not the disbelievers paid (fully) for what they used to do?

(1895) What is the matter with them, that they believe not?

(1896) And when the Qur'an is recited to them, they fall not prostrate.

(1897) Nay, those who disbelieve belie (Prophet Muhammad صلى الله عليه وسلم and whatever he brought, i.e. this Qur'an and Islamic Monotheism, etc.).

(1898) Verily, those who put into trial the believing men and believing women (by torturing them and burning them), and then do not turn in repentance (to Allah), then they will have the torment of Hell, and they will have the punishment of the burning Fire.

(1899) And He is Oft-Forgiving, full of love (towards the pious who are real true believers of Islamic Monotheism),

(1900) Nay! The disbelievers (persisted) in denying (Prophet Muhammad صلى الله عليه وسلم and his Message of Islamic Monotheism).
