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

(331) Your Lord knows you best; if He wills, He will have mercy on you, or if He wills, He will punish you. And We have not sent you (O Muhammad صلى الله عليه و سلم) as a guardian over them.

(332) And your Lord knows best all who are in the heavens and the earth. And indeed, We have preferred some of the Prophets above others, and to Dawud (David) We gave the Zabur (Psalms).

(333) Say (O Muhammad صلى الله عليه و سلم to mankind): "Each one does according to Shakilatihi (i.e. his way or his religion or his intentions.), and your Lord knows best of him whose path (religion) is right."

(334) And they ask you (O Muhammad صلى الله عليه و سلم) concerning the Ruh (the Spirit); Say: "The Ruh (the Spirit) is one of the things, the knowledge of which is only with my Lord. And of knowledge, you (mankind) have been given only a little."

(335) Say: "Sufficient is Allah for a witness between me and you. Verily He is Ever the All-knower, the All-Seer of His slaves."

(336) [Musa (Moses)] said: "Verily, you know that these signs have been sent down by none but the Lord of the heavens and the earth (as clear evidence i.e. proofs of Allah's Oneness and His Omnipotence.). And I think you are, indeed, O Fir'aun (Pharaoh) doomed to destruction (away from all good)!"

(337) Say (O Muhammad صلى الله عليه و سلم to them): "Believe in it (the Qur'an) or do not believe (in it). Verily those who were given knowledge before it (the Jews and the Christians like 'Abdullah bin Salam and Salman Al-Farisi), when it is recited to them, fall down on their faces in humble prostration."

(338) No knowledge have they of such a thing, nor had their fathers. Mighty is the word that comes out of their mouths [i.e. He begot sons and daughters]. They utter nothing but a lie .

(339) Likewise, We awakened them (from their long deep sleep) that they might question one another. A speaker from among them said: "How long have you stayed (here)?" They said: "We have stayed (perhaps) a day or part of a day." They said: "Your Lord (Alone) knows best how long you have stayed (here). So send one of you with this silver coin of yours to the town, and let him find out which is the good lawful food, and bring some of that to you. And let him be careful and let no man know of you.

(340) "For, if they come to know of you, they will stone you (to death or abuse and harm you) or turn you back to their religion; and in that case you will never be successful."
