The word(s) "tongue" appears 24 time(s) in 21 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Most surely there is a party amongst those who distort the Book with their tongue that you may consider it to be (a part) of the Book, and they say, It is from Allah, while it is not from Allah, and they tell a lie against Allah whilst they know.

(2) Of those who are Jews (there are those who) alter words from their places and say: We have heard and we disobey and: Hear, may you not be made to hear! and: Raina, distorting (the word) with their tongues and taunting about religion; and if they had said (instead): We have heard and we obey, and hearken, and unzurna it would have been better for them and more upright; but Allah has cursed them on account of their unbelief, so they do not believe but a little.

(3) Those who disbelieved from among the children of Israel were cursed by the tongue of Dawood and Isa, son of Marium; this was because they disobeyed and used to exceed the limit.

(4) And if We had pleased, We would certainly have exalted him thereby; but he clung to the earth and followed his low desire, so his parable is as the parable of the dog; if you attack him he lolls out his tongue; and if you leave him alone he lolls out his tongue; this is the parable of the people who reject Our communications; therefore relate the narrative that they may reflect.

(5) And they ascribe to Allah what they (themselves) hate and their tongues relate the lie that they shall have the good; there is no avoiding it that for them is the fire and that they shall be sent before.

(6) And certainly We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is clear Arabic tongue.

(7) And, for what your tongues describe, do not utter the lie, (saying) This is lawful and this is unlawful, in order to forge a lie against Allah; surely those who forge the lie against Allah shall not prosper.

(8) So We have only made it easy in your tongue that you may give good news thereby to those who guard (against evil) and warn thereby a vehemently contentious people.

(9) And loose the knot from my tongue,

(10) When you received it with your tongues and spoke with your mouths what you had no knowledge of, and you deemed it an easy matter while with Allah it was grievous.
