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

(51) Is he, then, to whom the evil of his conduct is made alluring, so that he looks upon it as good, (equal to one who is rightly guided)? For Allah leaves to stray whom He wills, and guides whom He wills. So let not thy soul go out in (vainly) sighing after them: for Allah knows well all that they do!

(52) Verily Allah knows (all) the hidden things of the heavens and the earth: verily He has full knowledge of all that is in (men's) hearts.

(53) (Allah) knows of (the tricks) that deceive with the eyes, and all that the hearts (of men) conceal.

(54) And if (at any time) an incitement to discord is made to thee by the Evil One, seek refuge in Allah. He is the One Who hears and knows all things.

(55) To Him is referred the Knowledge of the Hour (of Judgment: He knows all): No date-fruit comes out of its sheath, nor does a female conceive (within her womb) nor bring forth the Day that (Allah) will propound to them the (question), "Where are the partners (ye attributed to Me?" They will say, "We do assure thee not one of us can bear witness!"

(56) To Him belong the keys of the heavens and the earth: He enlarges and restricts. The Sustenance to whom He will: for He knows full well all things.

(57) What! Do they say, "He has forged a falsehood against Allah"? But if Allah willed, He could seal up thy heart. And Allah blots out Vanity, and proves the Truth by His Words. For He knows well the secrets of all hearts.

(58) He is the One that accepts repentance from His Servants and forgives sins: and He knows all that ye do.

(59) As Mercy from thy Lord: for He hears and knows (all things);

(60) Or do they say, "He has forged it"? Say: "Had I forged it, then can ye obtain no single (blessing) for me from Allah. He knows best of that whereof ye talk (so glibly)! Enough is He for a witness between me and you! And he is Oft-Forgiving, Most Merciful."
