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

(1631) Certainly Allah will admit those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, to Gardens under which rivers flow (Paradise); while those who disbelieve enjoy themselves and eat as cattle eat; and the Fire will be their abode.

(1632) The description of Paradise which the Muttaqun (the pious. See V.2:2) have been promised (is that) in it are rivers of water the taste and smell of which are not changed, rivers of milk of which the taste never changes, rivers of wine delicious to those who drink, and rivers of clarified honey (clear and pure) therein for them is every kind of fruit, and forgiveness from their Lord. (Are these) like those who shall dwell for ever in the Fire and be given to drink boiling water so that it cuts up their bowels?

(1633) Those who believe say: "Why is not a Surah (chapter of the Qur'an) sent down (for us)? But when a decisive Surah (explaining and ordering things) is sent down, and fighting (Jihad - holy fighting in Allah's cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allah and to obey Him).

(1634) Do they not then think deeply in the Qur'an, or are their hearts locked up (from understanding it)?

(1635) Or do those in whose hearts is a disease (of hypocrisy), think that Allah will not bring to light all their hidden ill-wills?

(1636) Verily, those who disbelieve, and hinder (men) from the Path of Allah (i.e. Islam), and oppose the Messenger (صلى الله عليه وسلم) (by standing against him and hurting him), after the guidance has been clearly shown to them, they will not harm Allah in the least, but He will make their deeds fruitless,

(1637) O you who believe! Obey Allah, and obey the Messenger (Muhammad صلى الله عليه وسلم) and render not vain your deeds.

(1638) Verily, those who disbelieve, and hinder (men) from the Path of Allah (i.e. Islam); then die while they are disbelievers - Allah will not forgive them.

(1639) So be not weak and ask not for peace (from the enemies of Islam) while you are having the upper hand. Allah is with you, and He will never decrease the reward of your good deeds.

(1640) The life of this world is but play and pastime; but if you believe (in the Oneness of Allah - Islamic Monotheism), and fear Allah, and avoid evil, He will grant you your wages, and will not ask you your wealth.
