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

(1041) And those who disbelieved will not cease to be in doubt about it (this Qur'an) until the Hour comes suddenly upon them, or there comes to them the torment of the Day after which there will be no night (i.e. the Day of Resurrection).

(1042) The sovereignty on that Day will be that of Allah (the One Who has no partners). He will judge between them. So those who believed (in the Oneness of Allah - Islamic Monotheism) and did righteous good deeds will be in Gardens of delight (Paradise).

(1043) See you not that Allah sends down water (rain) from the sky, and then the earth becomes green? Verily, Allah is the Most Kind and Courteous, Well-Acquainted with all things.

(1044) See you not that Allah has subjected to you (mankind) all that is on the earth, and the ships that sail through the sea by His Command? He withholds the heaven from falling on the earth except by His Leave. Verily, Allah is, for mankind, Full of Kindness, Most Merciful.

(1045) For every nation We have ordained religious ceremonies [e.g. slaughtering of the cattle during the three days of stay at Mina (Makkah) during the Hajj (pilgrimage)] which they must follow; so let them (the pagans) not dispute with you on the matter (i.e. to eat of the cattle which you slaughter, and not to eat of the cattle which Allah kills by its natural death), but invite them to your Lord. Verily you (O Muhammad صلى الله عليه وسلم) indeed are on the (true) straight guidance (i.e. the true religion of Islamic Monotheism).

(1046) Know you not that Allah knows all that is in the heaven and on the earth? Verily, it is (all) in the Book (Al-Lauh-al-Mahfuz). Verily that is easy for Allah.

(1047) And when Our Clear Verses are recited to them, you will notice a denial on the faces of the disbelievers! They are nearly ready to attack with violence those who recite Our Verses to them. Say: "Shall I tell you of something worse than that? The Fire (of Hell) which Allah has promised to those who disbelieved, and worst indeed is that destination!"

(1048) O mankind! A similitude has been coined, so listen to it (carefully): Verily those on whom you call besides Allah, cannot create (even) a fly, even though they combine together for the purpose. And if the fly snatches away a thing from them, they will have no power to release it from the fly. So weak are (both) the seeker and the sought.

(1049) They have not estimated Allah His Rightful Estimate. Verily, Allah is All-Strong, All-Mighty.

(1050) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!
