The word(s) "know" appears 656 time(s) in 561 verse(s) in Quran in Abdullah Yusuf Ali translation.

(361) "(Kept them away from the Path), that they should not worship Allah, Who brings to light what is hidden in the heavens and the earth, and knows what ye hide and what ye reveal.

(362) Said one who had knowledge of the Book: "I will bring it to thee within the twinkling of an eye!" Then when (Solomon) saw it placed firmly before him, he said: "This is by the Grace of my Lord!- to test me whether I am grateful or ungrateful! and if any is grateful, truly his gratitude is (a gain) for his own soul; but if any is ungrateful, truly my Lord is Free of all Needs, Supreme in Honour!"

(363) So when she arrived, she was asked, "Is this thy throne?" She said, "It was just like this; and knowledge was bestowed on us in advance of this, and we have submitted to Allah (in Islam)."

(364) Now such were their houses, - in utter ruin, - because they practised wrong-doing. Verily in this is a Sign for people of knowledge.

(365) Or, Who has made the earth firm to live in; made rivers in its midst; set thereon mountains immovable; and made a separating bar between the two bodies of flowing water? (can there be another) god besides Allah? Nay, most of them know not.

(366) Say: None in the heavens or on earth, except Allah, knows what is hidden: nor can they perceive when they shall be raised up (for Judgment).

(367) Still less can their knowledge comprehend the Hereafter: Nay, they are in doubt and uncertainty thereanent; nay, they are blind thereunto!

(368) And verily thy Lord knoweth all that their hearts do hide. As well as all that they reveal.

(369) Verily thy Lord will decide between them by His Decree: and He is Exalted in Might, All-knowing.

(370) Until, when they come (before the Judgment-seat), (Allah) will say: "Did ye reject My Signs, though ye comprehended them not in knowledge, or what was it ye did?"
