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

(531) Allah is He Who created seven Firmaments and of the earth a similar number. Through the midst of them (all) descends His Command: that ye may know that Allah has power over all things, and that Allah comprehends, all things in (His) knowledge.

(532) Allah has already ordained for you, (O men), the dissolution of your oaths (in some cases): and Allah is your Protector, and He is Full of knowledge and Wisdom.

(533) When the Prophet disclosed a matter in confidence to one of his consorts, and she then divulged it (to another), and Allah made it known to him, he confirmed part thereof and repudiated a part. Then when he told her thereof, she said, "Who told thee this? "He said, "He told me Who knows and is well-acquainted (with all things)."

(534) And whether ye hide your word or publish it, He certainly has (full) knowledge, of the secrets of (all) hearts.

(535) Should He not know,- He that created? and He is the One that understands the finest mysteries (and) is well-acquainted (with them).

(536) Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning?

(537) Say: "As to the knowledge of the time, it is with Allah alone: I am (sent) only to warn plainly in public."

(538) Say: "He is (Allah) Most Gracious: We have believed in Him, and on Him have we put our trust: So, soon will ye know which (of us) it is that is in manifest error."

(539) Verily it is thy Lord that knoweth best, which (among men) hath strayed from His Path: and He knoweth best those who receive (true) Guidance.

(540) And We certainly know that there are amongst you those that reject (it).
