The word(s) "knowledge" appears 128 time(s) in 124 verse(s) in Quran in Muhammad Pickthal translation.

(21) Yet they ascribe as partners unto Him the jinn, although He did create them, and impute falsely, without knowledge, sons and daughters unto Him. Glorified be He and High Exalted above (all) that they ascribe (unto Him).

(22) Thus do We display Our revelations that they may say (unto thee, Muhammad): "Thou hast studied," and that We may make (it) clear for people who have knowledge.

(23) 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.

(24) 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.

(25) 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.

(26) 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.

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

(28) 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.

(29) Verily We have brought them a Scripture which We expounded with knowledge, a guidance and a mercy for a people who believe.

(30) We should have invented a lie against Allah if we returned to your religion after Allah hath rescued us from it. It is not for us to return to it unless Allah our Lord should (so) will. Our Lord comprehendeth all things in knowledge. In Allah do we put our trust. Our Lord! Decide with truth between us and our folk, for Thou art the best of those who make decision.
