The word(s) "tongue" appears 21 time(s) in 20 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) There is among them a section who distort the Book with their tongues: (As they read) you would think it is a part of the Book, but it is no part of the Book; and they say, "That is from Allah," but it is not from Allah: It is they who tell a lie against Allah, and (well) they know it!

(2) Of the Jews there are those who displace words from their (right) places, and say: "We hear and we disobey"; and "Hear what is not Heard"; and "Ra'ina"; with a twist of their tongues and a slander to Faith. If only they had said: "What hear and we obey"; and "Do hear"; and "Do look at us"; it would have been better for them, and more proper; but Allah hath cursed them for their Unbelief; and but few of them will believe.

(3) Curses were pronounced on those among the Children of Israel who rejected Faith, by the tongue of David and of Jesus the son of Mary: because they disobeyed and persisted in excesses.

(4) If it had been Our will, We should have elevated him with Our signs; but he inclined to the earth, and followed his own vain desires. His similitude is that of a dog: if you attack him, he lolls out his tongue, or if you leave him alone, he (still) lolls out his tongue. That is the similitude of those who reject Our signs; So relate the story; perchance they may reflect.

(5) They attribute to Allah what they hate (for themselves), and their tongues assert the falsehood that all good things are for themselves: without doubt for them is the Fire, and they will be the first to be hastened on into it!

(6) We know indeed that they say, "It is a man that teaches him." The tongue of him they wickedly point to is notably foreign, while this is Arabic, pure and clear.

(7) But say not - for any false thing that your tongues may put forth,- "This is lawful, and this is forbidden," so as to ascribe false things to Allah. For those who ascribe false things to Allah, will never prosper.

(8) And We bestowed of Our Mercy on them, and We granted them lofty honour on the tongue of truth.

(9) So have We made the (Qur'an) easy in thine own tongue, that with it thou mayest give Glad Tidings to the righteous, and warnings to people given to contention.

(10) Behold, ye received it on your tongues, and said out of your mouths things of which ye had no knowledge; and ye thought it to be a light matter, while it was most serious in the sight of Allah.
