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

(481) He said: "The knowledge (of when it will come) is only with Allah: I proclaim to you the mission on which I have been sent: But I see that ye are a people in ignorance!"..

(482) And among them are men who listen to thee, but in the end, when they go out from thee, they say to those who have received knowledge, "What is it he said just then?" Such are men whose hearts Allah has sealed, and who follow their own lusts.

(483) know, therefore, that there is no god but Allah, and ask forgiveness for thy fault, and for the men and women who believe: for Allah knows how ye move about and how ye dwell in your homes.

(484) This, because they said to those who hate what Allah has revealed, "We will obey you in part of (this) matter"; but Allah knows their (inner) secrets.

(485) Had We so wiled, We could have shown them up to thee, and thou shouldst have known them by their marks: but surely thou wilt know them by the tone of their speech! And Allah knows all that ye do.

(486) It is He Who sent down tranquillity into the hearts of the Believers, that they may add faith to their faith;- for to Allah belong the Forces of the heavens and the earth; and Allah is Full of knowledge and Wisdom;-

(487) They are the ones who denied Revelation and hindered you from the Sacred Mosque and the sacrificial animals, detained from reaching their place of sacrifice. Had there not been believing men and believing women whom ye did not know that ye were trampling down and on whose account a crime would have accrued to you without (your) knowledge, (Allah would have allowed you to force your way, but He held back your hands) that He may admit to His Mercy whom He will. If they had been apart, We should certainly have punished the Unbelievers among them with a grievous Punishment.

(488) While the Unbelievers got up in their hearts heat and cant - the heat and cant of ignorance,- Allah sent down His Tranquillity to his Messenger and to the Believers, and made them stick close to the command of self-restraint; and well were they entitled to it and worthy of it. And Allah has full knowledge of all things.

(489) O Ye who believe! Put not yourselves forward before Allah and His Messenger; but fear Allah: for Allah is He Who hears and knows all things.

(490) And know that among you is Allah's Messenger: were he, in many matters, to follow your (wishes), ye would certainly fall into misfortune: But Allah has endeared the Faith to you, and has made it beautiful in your hearts, and He has made hateful to you Unbelief, wickedness, and rebellion: such indeed are those who walk in righteousness;-
