The word(s) "tongue" appears 19 time(s) in 17 verse(s) in Quran in Muhammad Pickthal translation.

(1) And lo! there is a party of them who distort the Scripture with their tongues, that ye may think that what they say is from the Scripture, when it is not from the Scripture. And they say: It is from Allah, when it is not from Allah; and they speak a lie concerning Allah knowingly.

(7) And We make (this Scripture) easy in thy tongue, (O Muhammad) only that thou mayst bear good tidings therewith unto those who ward off (evil), and warn therewith the froward folk.

(8) And loose a knot from my tongue,

(9) When ye welcomed it with your tongues, and uttered with your mouths that whereof ye had no knowledge, ye counted it a trifle. In the sight of Allah it is very great.
