The word(s) "knower" appears 18 time(s) in 18 verse(s) in Quran in Saheeh International translation.

(1) That is the bounty from Allah, and sufficient is Allah as knower.

(2) [Be warned of] the Day when Allah will assemble the messengers and say, "What was the response you received?" They will say, "We have no knowledge. Indeed, it is You who is knower of the unseen"

(3) 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.

(4) And it is He who created the heavens and earth in truth. And the day He says, "Be," and it is, His word is the truth. And His is the dominion [on] the Day the Horn is blown. [He is] knower of the unseen and the witnessed; and He is the Wise, the Acquainted.

(5) Did they not know that Allah knows their secrets and their private conversations and that Allah is the knower of the unseen?

(6) They will make excuses to you when you have returned to them. Say, "Make no excuse - never will we believe you. Allah has already informed us of your news. And Allah will observe your deeds, and [so will] His Messenger; then you will be taken back to the knower of the unseen and the witnessed, and He will inform you of what you used to do."

(7) And say, "Do [as you will], for Allah will see your deeds, and [so, will] His Messenger and the believers. And you will be returned to the knower of the unseen and the witnessed, and He will inform you of what you used to do."

(8) [He is] knower of the unseen and the witnessed, the Grand, the Exalted.

(9) [He is] knower of the unseen and the witnessed, so high is He above what they associate [with Him].

(10) That is the knower of the unseen and the witnessed, the Exalted in Might, the Merciful,
