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

(251) He (the king) (then sent for those women and) said: What happened when ye asked an evil act of Joseph? They answered: Allah Blameless! We know no evil of him. Said the wife of the ruler: Now the truth is out. I asked of him an evil act, and he is surely of the truthful.

(252) (Then Joseph said: I asked for) this, that he (my lord) may know that I betrayed him not in secret, and that surely Allah guideth not the snare of the betrayers.

(253) He said unto his young men: Place their merchandise in their saddlebags, so that they may know it when they go back to their folk, and so will come again.

(254) And when they entered in the manner which their father had enjoined, it would have naught availed them as against Allah; it was but a need of Jacob's soul which he thus satisfied; and lo! he was a lord of knowledge because We had taught him; but most of mankind know not.

(255) They said: By Allah, well ye know we came not to do evil in the land, and are no thieves.

(256) Then he (Joseph) began the search with their bags before his brother's bag, then he produced it from his brother's bag. Thus did We contrive for Joseph. He could not have taken his brother according to the king's law unless Allah willed. We raise by grades (of mercy) whom We will, and over every lord of knowledge there is one more knowing.

(257) They said: If he stealeth, a brother of his stole before. But Joseph kept it secret in his soul and revealed it not unto them. He said (within himself): Ye are in worse case, and Allah knoweth best (the truth of) that which ye allege.

(258) So, When they despaired of (moving) him, they conferred together apart. The eldest of them said: know ye not how your father took an undertaking from you in Allah's name and how ye failed in the case of Joseph aforetime? Therefore I shall not go forth from the land until my father giveth leave or Allah judgeth for me. He is the Best of Judges.

(259) Return unto your father and say: O our father! Lo! thy son hath stolen. We testify only to that which we know; we are not guardians of the Unseen.

(260) (And when they came unto their father and had spoken thus to him) he said: Nay, but your minds have beguiled you into something. (My course is) comely patience! It may be that Allah will bring them all unto me. Lo! He, only He, is the knower, the Wise.
