Deaf, dumb, blind - and they cannot turn back.

And so, the parable of those who re bent on denying the truth is that of the beast which hears the shepherd's cry, and hears in it nothing but the sound of a voice and a call.* Deaf are they, and dumb, and blind: for they do not use their reason.

And they who give the lie to Our messages are deaf and dumb, in darkness deep. Whomever God wills, He lets go astray; and whomever He wills, He places upon a straight way.*

Verily, the vilest of all creatures* in the sight of God are those deaf, those dumb ones who do not use their reason.

And God propounds [to you] the parable of two [other] men -one of them dumb,* unable to do anything of his own accord, and a sheer burden on his master: to whichever task the latter directs him,* he accomplishes no good. Can such a one be considered the equal of [a wise man] who enjoins the doing of what is right and himself follows a straight way?*

And he whom God guides, he alone has found the right way; whereas for those whom He lets go astray thou canst never find anyone to protect them from Him: and [so, when] We shall gather them together on the Day of Resurrection, [they will lie] prone upon their faces, blind and dumb and deaf, with hell as their goal; [and] every time [the fire] abates, We shall increase for them [its] blazing flame.*
