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

(141) When there comes to them a sign (from Allah), They say: "We shall not believe until we receive one (exactly) like those received by Allah's messengers." Allah knoweth best where (and how) to carry out His mission. Soon will the wicked be overtaken by humiliation before Allah, and a severe punishment, for all their plots.

(142) One day will He gather them all together, (and say): "O ye assembly of Jinns! Much (toll) did ye take of men." Their friends amongst men will say: "Our Lord! we made profit from each other: but (alas!) we reached our term - which thou didst appoint for us." He will say: "The Fire be your dwelling-place: you will dwell therein for ever, except as Allah willeth." for thy Lord is full of wisdom and knowledge.

(143) Say: "O my people! Do whatever ye can: I will do (my part): soon will ye know who it is whose end will be (best) in the Hereafter: certain it is that the wrong-doers will not prosper."

(144) They say: "What is in the wombs of such and such cattle is specially reserved (for food) for our men, and forbidden to our women; but if it is still-born, then all have share therein. For their (false) attribution (of superstitions to Allah), He will soon punish them: for He is full of wisdom and knowledge.

(145) Lost are those who slay their children, from folly, without knowledge, and forbid food which Allah hath provided for them, inventing (lies) against Allah. They have indeed gone astray and heeded no guidance.

(146) (Take) eight (head of cattle) in (four) pairs: of sheep a pair, and of goats a pair; say, hath He forbidden the two males, or the two females, or (the young) which the wombs of the two females enclose? Tell me with knowledge if ye are truthful:

(147) Of camels a pair, and oxen a pair; say, hath He forbidden the two males, or the two females, or (the young) which the wombs of the two females enclose? - Were ye present when Allah ordered you such a thing? But who doth more wrong than one who invents a lie against Allah, to lead astray men without knowledge? For Allah guideth not people who do wrong.

(148) Those who give partners (to Allah) will say: "If Allah had wished, we should not have given partners to Him nor would our fathers; nor should we have had any taboos." So did their ancestors argue falsely, until they tasted of Our wrath. Say: "Have ye any (certain) knowledge? If so, produce it before us. Ye follow nothing but conjecture: ye do nothing but lie."

(149) And verily, We shall recount their whole story with knowledge, for We were never absent (at any time or place).

(150) When they do aught that is shameful, they say: "We found our fathers doing so"; and "Allah commanded us thus": Say: "Nay, Allah never commands what is shameful: do ye say of Allah what ye know not?"
