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

(561) They say: Surely, if we return to Al-Madinah the mightier will soon drive out the weaker; when might belongeth to Allah and to His messenger and to the believers; but the hypocrites know not.

(562) He knoweth all that is in the heavens and the earth, and He knoweth what ye conceal and what ye publish. And Allah is Aware of what is in the breasts (of men).

(563) No calamity befalleth save by Allah's leave. And whosoever believeth in Allah, He guideth his heart. And Allah is knower of all things.

(564) knower of the Invisible and the Visible, the Mighty, the Wise.

(565) O Prophet! When ye (men) put away women, put them away for their (legal) period and reckon the period, and keep your duty to Allah, your Lord. Expel them not from their houses nor let them go forth unless they commit open immorality. Such are the limits (imposed by) Allah; and whoso transgresseth Allah's limits, he verily wrongeth his soul. Thou knowest not: it may be that Allah will afterward bring some new thing to pass.

(566) Allah it is who hath created seven heavens, and of the earth the like thereof. The commandment cometh down among them slowly, that ye may know that Allah is Able to do all things, and that Allah surroundeth all things in knowledge.

(567) Allah hath made lawful for you (Muslims) absolution from your oaths (of such a kind), and Allah is your Protector. He is the knower, the Wise.

(568) When the Prophet confided a fact unto one of his wives and when she afterward divulged it and Allah apprised him thereof, he made known (to her) part thereof and passed over part. And when he told it her she said: Who hath told thee? He said: The knower, the Aware hath told me.

(569) So they acknowledge their sins; but far removed (from mercy) are the dwellers in the flames.

(570) And keep your opinion secret or proclaim it, lo! He is knower of all that is in the breasts (of men).
