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

(151) They are losers who besottedly have slain their children without knowledge, and have forbidden that which Allah bestowed upon them, inventing a lie against Allah. They indeed have gone astray and are not guided.

(152) Eight pairs: Of the sheep twain, and of the goats twain. Say: Hath He forbidden the two males or the two females, or that which the wombs of the two females contain? Expound to me (the case) with knowledge, if ye are truthful.

(153) And of the camels twain and of the oxen twain. Say: Hath He forbidden the two males or the two females, or that which the wombs of the two females contain; or were ye by to witness when Allah commanded you (all) this? Then who doth greater wrong than he who deviseth a lie concerning Allah, that he may lead mankind astray without knowledge. Lo! Allah guideth not wrongdoing folk.

(154) They who are idolaters will say: Had Allah willed, we had not ascribed (unto Him) partners neither had our fathers, nor had we forbidden aught. Thus did those who were before them give the lie (to Allah's messengers) till they tasted of the fear of Us. Say: Have ye any knowledge that ye can adduce for Us? Lo! ye follow naught but an opinion, Lo! ye do but guess.

(155) Then verily We shall narrate unto them (the event) with knowledge, for We were not absent (when it came to pass).

(156) And when they do some lewdness they say: We found our fathers doing it and Allah hath enjoined it on us. Say: Allah, verily, enjoineth not lewdness. Tell ye concerning Allah that which ye know not?

(157) Say: Who hath forbidden the adornment of Allah which He hath brought forth for His bondmen, and the good things of His providing? Say: Such, on the Day of Resurrection, will be only for those who believed during the life of the world. Thus do we detail Our revelations for people who have knowledge.

(158) Say: My Lord forbiddeth only indecencies, such of them as are apparent and such as are within, and sin and wrongful oppression, and that ye associate with Allah that for which no warrant hath been revealed, and that ye tell concerning Allah that which ye know not.

(159) He saith: Enter into the Fire among nations of the jinn and humankind who passed away before you. Every time a nation entereth, it curseth its sister (nation) till, when they have all been made to follow one another thither, the last of them saith unto the first of them: Our Lord! These led us astray, so give them double torment of the Fire. He saith: For each one there is double (torment), but ye know not.

(160) Between them is a veil. And on the Heights are men who know them all by their marks. And they call unto the dwellers of the Garden: Peace be unto you! They enter it not although they hope (to enter).
