The word(s) "know" appears 694 time(s) in 606 verse(s) in Quran in Muhammad Pickthal translation.

(421) It is a promise of Allah. Allah faileth not His promise, but most of mankind know not.

(422) They know only some appearance of the life of the world, and are heedless of the Hereafter.

(423) And of His signs is the creation of the heavens and the earth, and the difference of your languages and colours. Lo! herein indeed are portents for men of knowledge.

(424) Nay, but those who do wrong follow their own lusts without knowledge. Who is able to guide him whom Allah hath sent astray? For such there are no helpers.

(425) So set thy purpose (O Muhammad) for religion as a man by nature upright - the nature (framed) of Allah, in which He hath created man. There is no altering (the laws of) Allah's creation. That is the right religion, but most men know not -

(426) So as to disbelieve in that which We have given them. (Unto such it is said): Enjoy yourselves awhile, but ye will come to know.

(427) Allah is He Who shaped you out of weakness, then appointed after weakness strength, then, after strength, appointed weakness and grey hair. He createth what He will. He is the knower, the Mighty.

(428) But those to whom knowledge and faith are given will say: The truth is, ye have tarried, by Allah's decree, until the Day of Resurrection. This is the Day of Resurrection, but ye used not to know.

(429) Thus doth Allah seal the hearts of those who know not.

(430) And of mankind is he who payeth for mere pastime of discourse, that he may mislead from Allah's way without knowledge, and maketh it the butt of mockery. For such there is a shameful doom.
