The word(s) "known" appears 43 time(s) in 41 verse(s) in Quran in Saheeh International translation.

(1) And you had already known about those who transgressed among you concerning the sabbath, and We said to them, "Be apes, despised."

(2) Hajj is [during] well-known months, so whoever has made Hajj obligatory upon himself therein [by entering the state of ihram], there is [to be for him] no sexual relations and no disobedience and no disputing during Hajj. And whatever good you do - Allah knows it. And take provisions, but indeed, the best provision is fear of Allah. And fear Me, O you of understanding.

(3) And that He might make evident those who are hypocrites. For it was said to them, "Come, fight in the way of Allah or [at least] defend." They said, "If we had known [there would be] fighting, we would have followed you." They were nearer to disbelief that day than to faith, saying with their mouths what was not in their hearts. And Allah is most Knowing of what they conceal -

(4) And when there comes to them information about [public] security or fear, they spread it around. But if they had referred it back to the Messenger or to those of authority among them, then the ones who [can] draw correct conclusions from it would have known about it. And if not for the favor of Allah upon you and His mercy, you would have followed Satan, except for a few.

(5) And [beware the Day] when Allah will say, "O Jesus, Son of Mary, did you say to the people, 'Take me and my mother as deities besides Allah?'" He will say, "Exalted are You! It was not for me to say that to which I have no right. If I had said it, You would have known it. You know what is within myself, and I do not know what is within Yourself. Indeed, it is You who is Knower of the unseen.

(6) It is He who created you from clay and then decreed a term and a specified time [known] to Him; then [still] you are in dispute.

(7) Had Allah known any good in them, He would have made them hear. And if He had made them hear, they would [still] have turned away, while they were refusing.

(8) Say, "If Allah had willed, I would not have recited it to you, nor would He have made it known to you, for I had remained among you a lifetime before it. Then will you not reason?"

(9) They said, "You have already known that we have not concerning your daughters any claim, and indeed, you know what we want."

(10) And the brothers of Joseph came [seeking food], and they entered upon him; and he recognized them, but he was to them unknown.
