The word(s) "knower" appears 31 time(s) in 31 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) And those who disbelieve say: The hour shall not come upon us. Say: Yea! by my Lord, the knower of the unseen, it shall certainly come upon you; not the weight of an atom becomes absent from Him, in the heavens or in the earth, and neither less than that nor greater, but (all) is in a clear book

(22) Say: Surely my Lord utters the truth, the great knower of the unseen.

(23) Surely Allah is the knower of what is unseen in the heavens and the earth; surely He is Cognizant of what is in the hearts.

(24) Is not He Who created the heavens and the earth able to create the like of them? Yea! and He is the Creator (of all), the knower.

(25) Say: O Allah! Originator of the heavens and the earth, knower of the unseen and the seen! Thou (only) judgest between Thy servants as to that wherein they differ.

(26) He is the First and the Last and the Ascendant (over all) and the knower of hidden things, and He is Cognizant of all things.

(27) He is Allah besides Whom there is no god; the knower of the unseen and the seen; He is the Beneficent, the Merciful

(28) Say: (As for) the death from which you flee, that will surely overtake you, then you shall be sent back to the knower of the unseen and the seen, and He will inform you of that which you did.

(29) The knower of the unseen and the seen, the Mighty, the Wise.

(30) Does He not know, Who created? And He is the knower of the subtleties, the Aware.
