The word(s) "falsely" appears 6 time(s) in 6 verse(s) in Quran in Muhammad Pickthal translation.

(1) And follow that which the devils falsely related against the kingdom of Solomon. Solomon disbelieved not; but the devils disbelieved, teaching mankind magic and that which was revealed to the two angels in Babel, Harut and Marut. Nor did they (the two angels) teach it to anyone till they had said: We are only a temptation, therefore disbelieve not (in the guidance of Allah). And from these two (angles) people learn that by which they cause division between man and wife; but they injure thereby no-one save by Allah's leave. And they learn that which harmeth them and profiteth them not. And surely they do know that he who trafficketh therein will have no (happy) portion in the Hereafter; and surely evil is the price for which they sell their souls, if they but knew.

(2) 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).

(3) And We know well that they say: Only a man teacheth him. The speech of him at whom they falsely hint is outlandish, and this is clear Arabic speech.

(4) Then Moses threw his staff and lo! it swallowed that which they did falsely show.

(5) The folk of Noah and the factions after them denied (their messengers) before these, and every nation purposed to seize their messenger and argued falsely, (thinking) thereby to refute the Truth. Then I seized them, and how (awful) was My punishment.

(6) When the hypocrites come unto thee (O Muhammad), they say: We bear witness that thou art indeed Allah's messenger. And Allah knoweth that thou art indeed His messenger, and Allah beareth witness that the hypocrites indeed are speaking falsely.
