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

(11) They will excuse themselves to you when you go back to them. Say: Urge no excuse, by no means will we believe you; indeed Allah has informed us of matters relating to you; and now Allah and His Apostle will see your doings, then you shall be brought back to the knower of the unseen and the seen, then He will inform you of what you did.

(12) And say: Work; so Allah will see your work and (so will) His Apostle and the believers; and you shall be brought back to the knower of the unseen and the seen, then He will inform you of what you did.

(13) The knower of the unseen and the seen, the Great, the Most High.

(14) And (We made subservient) to Sulaiman the wind blowing violent, pursuing its course by his command to the land which We had blessed, and We are knower of all things.

(15) The knower of the unseen and the seen, so may He be exalted above what they associate (with Him).

(16) And among men is he who says: We believe in Allah; but when he is persecuted in (the way of) Allah he thinks the persecution of men to be as the chastisement of Allah; and if there come assistance from your Lord, they would most certainly say: Surely we were with you. What! is not Allah the best knower of what is in the breasts of mankind.

(17) O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is knower of subtleties, Aware;

(18) And whoever disbelieves, let not his disbelief grieve you; to Us is their return, then will We inform them of what they did surely Allah is the knower of what is in the breasts.

(19) This is the knower of the unseen and the seen, the Mighty the Merciful,

(20) And keep to mind what is recited in your houses of the communications of Allah and the wisdom; surely Allah is knower of subtleties, Aware.
