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

(321) Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of knowledge and Wisdom:

(322) And that those on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way.

(323) Verily He will admit them to a place with which they shall be well pleased: for Allah is All-knowing, Most Forbearing.

(324) If they do wrangle with thee, say, "Allah knows best what it is ye are doing."

(325) knowest thou not that Allah knows all that is in heaven and on earth? Indeed it is all in a Record, and that is easy for Allah.

(326) Yet they worship, besides Allah, things for which no authority has been sent down to them, and of which they have (really) no knowledge: for those that do wrong there is no helper.

(327) He knows what is before them and what is behind them: and to Allah go back all questions (for decision).

(328) Say: "To whom belong the earth and all beings therein? (say) if ye know!"

(329) Say: "Who is it in whose hands is the governance of all things,- who protects (all), but is not protected (of any)? (say) if ye know."

(330) He knows what is hidden and what is open: too high is He for the partners they attribute to Him!
