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

(231) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. These are the Verses of the Book (the Qur'an) Al-Hakim

(232) It is He Who made the sun a shining thing and the moon as a light and measured out for it stages that you might know the number of years and the reckoning. Allah did not create this but in truth. He explains the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in detail for people who have knowledge.

(233) Say (O Muhammad صلى الله عليه وسلم): "If Allah had so willed, I should not have recited it to you nor would He have made it known to you. Verily, I have stayed amongst you a life time before this. Have you then no sense?"

(234) And they worship besides Allah things that harm them not, nor profit them, and they say: "These are our intercessors with Allah." Say: "Do you inform Allah of that which He knows not in the heavens and on the earth?" Glorified and Exalted is He above all that which they associate as partners (with Him)!

(235) There! Every person will know (exactly) what he had earned before and they will be brought back to Allah, their rightful Maula (Lord), and their invented false deities will vanish from them.

(236) Nay, they have belied the knowledge whereof they could not comprehend and what has not yet been fulfilled (i.e. their punishment). Thus those before them did belie. Then see what was the end of the Zalimun (polytheists and wrong-doers)!

(237) No doubt, surely, all that is in the heavens and the earth belongs to Allah. No doubt, surely, Allah's Promise is true. But most of them know not.

(238) And let not their speech grieve you (O Muhammad صلى الله عليه وسلم), for all power and honour belong to Allah. He is the All-Hearer, the All-knower.

(239) They (Jews, Christians and pagans) say: "Allah has begotten a son (children)." Glory is to Him! He is Rich (Free of all needs). His is all that is in the heavens and all that is in the earth. No warrant you have for this. Do you say against Allah what you know not.

(240) Allah said: "Verily, the invocation of you both is accepted. So you both keep to the Straight Way (i.e. keep on doing good deeds and preaching Allah's Message with patience), and follow not the path of those who know not (the truth i.e. to believe in the Oneness of Allah, and also to believe in the Reward of Allah: Paradise)."
