The word(s) "dumb" appears 9 time(s) in 9 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Deaf, dumb, and blind, they will not return (to the path).

(2) The parable of those who reject Faith is as if one were to shout Like a goat-herd, to things that listen to nothing but calls and cries: Deaf, dumb, and blind, they are void of wisdom.

(3) Those who reject our signs are deaf and dumb,- in the midst of darkness profound: whom Allah willeth, He leaveth to wander: whom He willeth, He placeth on the way that is straight.

(4) For the worst of beasts in the sight of Allah are the deaf and the dumb,- those who understand not.

(5) Allah sets forth (another) Parable of two men: one of them dumb, with no power of any sort; a wearisome burden is he to his master; whichever way be directs him, he brings no good: is such a man equal with one who commands Justice, and is on a Straight Way?

(6) It is he whom Allah guides, that is on true Guidance; but he whom He leaves astray - for such wilt thou find no protector besides Him. On the Day of Judgment We shall gather, them together, prone on their faces, blind, dumb, and deaf: their abode will be Hell: every time it shows abatement, We shall increase from them the fierceness of the Fire.

(7) (Zakariya) said: "O my Lord! give me a Sign." "Thy Sign," was the answer, "Shall be that thou shalt speak to no man for three nights, although thou art not dumb."

(8) On the Day that the Hour will be established, the guilty will be struck dumb with despair.

(9) Even though, before they received (the rain) - just before this - they were dumb with despair!
