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

(201) And Allah will not mislead a people after He hath guided them, in order that He may make clear to them what to fear (and avoid)- for Allah hath knowledge of all things.

(202) O ye who believe! fight the unbelievers who gird you about, and let them find firmness in you: and know that Allah is with those who fear Him.

(203) It is He Who made the sun to be a shining glory and the moon to be a light (of beauty), and measured out stages for her; that ye might know the number of years and the count (of time). Nowise did Allah create this but in truth and righteousness. (Thus) doth He explain His Signs in detail, for those who understand.

(204) Say: "If Allah had so willed, I should not have rehearsed it to you, nor would He have made it known to you. A whole life-time before this have I tarried amongst you: will ye not then understand?"

(205) They serve, besides Allah, things that hurt them not nor profit them, and they say: "These are our intercessors with Allah." Say: "Do ye indeed inform Allah of something He knows not, in the heavens or on earth?- Glory to Him! and far is He above the partners they ascribe (to Him)!"

(206) They say: "Why is not a sign sent down to him from his Lord?" Say: "The Unseen is only for Allah (to know), then wait ye: I too will wait with you."

(207) Nay, they charge with falsehood that whose knowledge they cannot compass, even before the elucidation thereof hath reached them: thus did those before them make charges of falsehood: but see what was the end of those who did wrong!

(208) Of them there are some who believe therein, and some who do not: and thy Lord knoweth best those who are out for mischief.

(209) Let not their speech grieve thee: for all power and honour belong to Allah: It is He Who heareth and knoweth (all things).

(210) They say: "Allah hath begotten a son!" - Glory be to Him! He is self-sufficient! His are all things in the heavens and on earth! No warrant have ye for this! say ye about Allah what ye know not?
