The word(s) "know" appears 656 time(s) in 561 verse(s) in Quran in Abdullah Yusuf Ali translation.

(441) Is one who worships devoutly during the hour of the night prostrating himself or standing (in adoration), who takes heed of the Hereafter, and who places his hope in the Mercy of his Lord - (like one who does not)? Say: "Are those equal, those who know and those who do not know? It is those who are endued with understanding that receive admonition.

(442) Allah puts forth a Parable a man belonging to many partners at variance with each other, and a man belonging entirely to one master: are those two equal in comparison? Praise be to Allah! but most of them have no knowledge.

(443) Say: "O my People! Do whatever ye can: I will do (my part): but soon will ye know-

(444) Say: "O Allah! Creator of the heavens and the earth! knower of all that is hidden and open! it is Thou that wilt judge between Thy Servants in those matters about which they have differed."

(445) Now, when trouble touches man, he cries to Us: But when We bestow a favour upon him as from Ourselves, he says, "This has been given to me because of a certain knowledge (I have)!" Nay, but this is but a trial, but most of them understand not!

(446) know they not that Allah enlarges the provision or restricts it, for any He pleases? Verily, in this are Signs for those who believe!

(447) And to every soul will be paid in full (the fruit) of its Deeds; and (Allah) knoweth best all that they do.

(448) The revelation of this Book is from Allah, Exalted in Power, Full of knowledge,-

(449) Those who sustain the Throne (of Allah) and those around it Sing Glory and Praise to their Lord; believe in Him; and implore Forgiveness for those who believe: "Our Lord! Thy Reach is over all things, in Mercy and knowledge. Forgive, then, those who turn in Repentance, and follow Thy Path; and preserve them from the Penalty of the Blazing Fire!

(450) (Allah) knows of (the tricks) that deceive with the eyes, and all that the hearts (of men) conceal.
