The word(s) "knows" appears 80 time(s) in 75 verse(s) in Quran in Abdullah Yusuf Ali translation.

(61) Know, therefore, that there is no god but Allah, and ask forgiveness for thy fault, and for the men and women who believe: for Allah knows how ye move about and how ye dwell in your homes.

(62) This, because they said to those who hate what Allah has revealed, "We will obey you in part of (this) matter"; but Allah knows their (inner) secrets.

(63) Had We so wiled, We could have shown them up to thee, and thou shouldst have known them by their marks: but surely thou wilt know them by the tone of their speech! And Allah knows all that ye do.

(64) O Ye who believe! Put not yourselves forward before Allah and His Messenger; but fear Allah: for Allah is He Who hears and knows all things.

(65) Say: "What! Will ye instruct Allah about your religion? But Allah knows all that is in the heavens and on earth: He has full knowledge of all things.

(66) "Verily Allah knows the secrets of the heavens and the earth: and Allah Sees well all that ye do."

(67) Those who avoid great sins and shameful deeds, only (falling into) small faults,- verily thy Lord is ample in forgiveness. He knows you well when He brings you out of the earth, And when ye are hidden in your mothers' wombs. Therefore justify not yourselves: He knows best who it is that guards against evil.

(68) He it is Who created the heavens and the earth in Six Days, and is moreover firmly established on the Throne (of Authority). He knows what enters within the earth and what comes forth out of it, what comes down from heaven and what mounts up to it. And He is with you wheresoever ye may be. And Allah sees well all that ye do.

(69) Allah is He, than Whom there is no other god;- Who knows (all things) both secret and open; He, Most Gracious, Most Merciful.

(70) O ye who believe! When there come to you believing women refugees, examine (and test) them: Allah knows best as to their Faith: if ye ascertain that they are Believers, then send them not back to the Unbelievers. They are not lawful (wives) for the Unbelievers, nor are the (Unbelievers) lawful (husbands) for them. But pay the Unbelievers what they have spent (on their dower), and there will be no blame on you if ye marry them on payment of their dower to them. But hold not to the guardianship of unbelieving women: ask for what ye have spent on their dowers, and let the (Unbelievers) ask for what they have spent (on the dowers of women who come over to you). Such is the command of Allah: He judges (with justice) between you. And Allah is Full of Knowledge and Wisdom.
