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

(281) All-knower of the Unseen and the seen, the Most Great, the Most High.

(282) Shall he then who knows that what has been revealed unto you (O Muhammad صلى الله عليه و سلم) from your Lord is the truth be like him who is blind? But it is only the men of understanding that pay heed.

(283) And if there had been a Qur'an with which mountains could be moved (from their places), or the earth could be cloven asunder, or the dead could be made to speak (it would not have been other than this Qur'an). But the decision of all things is certainly with Allah. Have not then those who believed yet known that had Allah willed, He could have guided all mankind? And a disaster will not cease to strike those who disbelieved because of their (evil) deeds or it (i.e. the disaster) settles close to their homes, until the Promise of Allah comes to pass. Certainly, Allah breaks not His Promise.

(284) Is then He (Allah) Who takes charge (guards, maintains, provides) of every person and knows all that he has earned (like any other deities who know nothing)? Yet, they ascribe partners to Allah. Say: "Name them! Is it that you will inform Him of something He knows not in the earth or is it (just) a show of false words." Nay! To those who disbelieved, their plotting is made fairseeming, and they have been hindered from the Right Path; and whom Allah sends astray, for him there is no guide.

(285) And thus have We sent it (the Qur'an) down to be a judgement of authority in Arabic. Were you (O Muhammad صلى الله عليه و سلم) to follow their (vain) desires after the knowledge which has come to you, then you will not have any Wali (protector) or Waq (defender) against Allah.

(286) And verily, those before them did devise plots, but all planning is Allah's. He knows what every person earns, and the disbelievers will know who gets the good end (final destination).

(287) And those who disbelieved, say: "You (O Muhammad صلى الله عليه و سلم) are not a Messenger." Say: "Sufficient as a witness between me and you is Allah and those too who have knowledge of the Scripture (such as 'Abdullah bin Salam and other Jews and Christians who embraced Islam)."

(288) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. (This is) a Book which We have revealed unto you (O Muhammad صلى الله عليه و سلم) in order that you might lead mankind out of darkness (of disbelief and polytheism) into light (of belief in the Oneness of Allah and Islamic Monotheism) by their Lord's Leave to the Path of the All-Mighty, the Owner of all Praise.

(289) Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)."

(290) "O our Lord! Certainly, You know what we conceal and what we reveal. Nothing on the earth or in the heaven is hidden from Allah.
