The word(s) "know" appears 814 time(s) in 684 verse(s) in Quran in Mohsin Khan translation.

(601) That is what they could reach of knowledge. Verily, your Lord it is He Who knows best him who goes astray from His Path, and He knows best him who receives guidance.

(602) Those who avoid great sins (See the Qur'an, Verses: 6:152,153) and Al-Fawahish (illegal sexual intercourse) except the small faults, - verily, your Lord is of Vast Forgiveness. He knows you well when He created you from the earth (Adam), and when you were fetuses in your mothers' wombs. So ascribe not purity to yourselves. He knows best him who fears Allah and keeps his duty to Him [i.e. those who are Al-Muttaqun (the pious. See V.2:2)].

(603) Is with him the knowledge of the Unseen so that he sees?

(604) Tomorrow they will come to know who is the liar, the insolent one!

(605) So on that Day no question will be asked of man or jinns as to his sin, [because they have already been known from their faces either white (dwellers of Paradise - true believers of Islamic Monotheism) or black (dwellers of Hell - polytheists; disbelievers, criminals)].

(606) The Mujrimun (polytheists, criminals, sinners) will be known by their marks (black faces), and they will be seized by their forelocks and their feet.

(607) "All will surely be gathered together for appointed Meeting of a known Day.

(608) To transfigure you and create you in (forms) that you know not.

(609) And indeed, you have already known the first form of creation (i.e. the creation of Adam): why then do you not remember (or take heed)?

(610) And verily that is indeed a great oath, if you but know.
