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

(1561) Shall We then (warn you not and) take away the Reminder (this Qur'an) from you, because you are a people Musrifun.

(1562) (Like they then for Allah) a creature who is brought up in adornments (wearing silk and gold ornaments, i.e. women), and who in dispute cannot make herself clear?

(1563) And they said: "If it had been the Will of the Most Gracious (Allah), we should not have worshipped them (false deities)." They have no knowledge whatsoever of that. They do nothing but lie!

(1564) And similarly, We sent not a warner before you (O Muhammad صلى الله عليه و سلم) to any town (people) but the luxurious ones among them said: "We found our fathers following a certain way and religion, and we will indeed follow their footsteps."

(1565) So We took revenge on them, then see what was the end of those who denied (Islamic Monotheism).

(1566) And he made it [i.e. La ilaha illallah (none has the right to be worshipped but Allah Alone)] a Word lasting among his offspring, (True Monotheism), that they may turn back (i.e. to repent to Allah or receive admonition).

(1567) And they say: "Why is not this Qur'an sent down to some great man of the two towns (Makkah and Ta'if)?"

(1568) And were it not that mankind would have become of one community (all disbelievers, desiring worldly life only), We would have provided for those who disbelieve in the Most Gracious (Allah), silver roofs for their houses, and elevators whereby they ascend,

(1569) And adornments of gold. Yet all this (i.e. the roofs, doors, stairs, elevators, thrones of their houses) would have been nothing but an enjoyment of this world. And the Hereafter with your Lord is (only) for the Muttaqun.

(1570) It will profit you not this Day (O you who turn away from Allah's remembrance and His worship) as you did wrong, (and) that you will be sharers (you and your Qarin ) in the punishment.
