The word(s) "know" appears 694 time(s) in 606 verse(s) in Quran in Muhammad Pickthal translation.

(341) And unto Lot we gave judgment and knowledge, and We delivered him from the community that did abominations. Lo! they were folk of evil, lewd.

(342) And We made Solomon to understand (the case); and unto each of them We gave judgment and knowledge. And we subdued the hills and the birds to hymn (His) praise along with David. We were the doers (thereof).

(343) But if they are averse, then say: I have warned you all alike, although I know not whether nigh or far is that which ye are promised.

(344) Lo! He knoweth that which is said openly, and that which ye conceal.

(345) And I know not but that this may be a trial for you, and enjoyment for a while.

(346) Among mankind is he who disputeth concerning Allah without knowledge, and followeth each froward devil;

(347) O mankind! if ye are in doubt concerning the Resurrection, then lo! We have created you from dust, then from a drop of seed, then from a clot, then from a little lump of flesh shapely and shapeless, that We may make (it) clear for you. And We cause what We will to remain in the wombs for an appointed time, and afterward We bring you forth as infants, then (give you growth) that ye attain your full strength. And among you there is he who dieth (young), and among you there is he who is brought back to the most abject time of life, so that, after knowledge, he knoweth naught. And thou (Muhammad) seest the earth barren, but when We send down water thereon, it doth thrill and swell and put forth every lovely kind (of growth).

(348) And among mankind is he who disputeth concerning Allah without knowledge or guidance or a scripture giving light,

(349) Never sent We a messenger or a prophet before thee but when He recited (the message) Satan proposed (opposition) in respect of that which he recited thereof. But Allah abolisheth that which Satan proposeth. Then Allah establisheth His revelations. Allah is knower, Wise;

(350) And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right path.
