The word(s) "not" appears 1997 time(s) in 1622 verse(s) in Quran in Muhammad Pickthal translation.

(1431) Is this magic, or do ye not see?

(1432) Or say they: He hath invented it? Nay, but they will not believe!

(1433) Or did they create the heavens and the earth? Nay, but they are sure of nothing!

(1434) And verily, for those who do wrong, there is a punishment beyond that. But most of them know not.

(1435) Your comrade erreth not, nor is deceived;

(1436) The heart lied not (in seeing) what it saw.

(1437) And verily he saw him yet another time

(1438) The eye turned not aside nor yet was overbold.

(1439) Those who avoid enormities of sin and abominations, save the unwilled offences - (for them) lo! thy Lord is of vast mercy. He is Best Aware of you (from the time) when He created you from the earth, and when ye were hidden in the bellies of your mothers. Therefor ascribe not purity unto yourselves. He is Best Aware of him who wardeth off (evil).

(1440) Or hath he not had news of what is in the books of Moses
