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

(161) Say: "I have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith."

(162) If a suggestion from Satan assail thy (mind), seek refuge with Allah; for He heareth and knoweth (all things).

(163) It is not ye who slew them; it was Allah: when thou threwest (a handful of dust), it was not thy act, but Allah's: in order that He might test the Believers by a gracious trial from Himself: for Allah is He Who heareth and knoweth (all things).

(164) O ye who believe! give your response to Allah and His Messenger, when He calleth you to that which will give you life; and know that Allah cometh in between a man and his heart, and that it is He to Whom ye shall (all) be gathered.

(165) And fear tumult or oppression, which affecteth not in particular (only) those of you who do wrong: and know that Allah is strict in punishment.

(166) O ye that believe! betray not the trust of Allah and the Messenger, nor misappropriate knowingly things entrusted to you.

(167) And know ye that your possessions and your progeny are but a trial; and that it is Allah with Whom lies your highest reward.

(168) And know that out of all the booty that ye may acquire (in war), a fifth share is assigned to Allah,- and to the Messenger, and to near relatives, orphans, the needy, and the wayfarer,- if ye do believe in Allah and in the revelation We sent down to Our servant on the Day of Testing,- the Day of the meeting of the two forces. For Allah hath power over all things.

(169) Remember ye were on the hither side of the valley, and they on the farther side, and the caravan on lower ground than ye. Even if ye had made a mutual appointment to meet, ye would certainly have failed in the appointment: But (thus ye met), that Allah might accomplish a matter already enacted; that those who died might die after a clear Sign (had been given), and those who lived might live after a Clear Sign (had been given). And verily Allah is He Who heareth and knoweth (all things).

(170) Remember in thy dream Allah showed them to thee as few: if He had shown them to thee as many, ye would surely have been discouraged, and ye would surely have disputed in (your) decision; but Allah saved (you): for He knoweth well the (secrets) of (all) hearts.
