﴿ صُمٌّۢ بُكْمٌ عُمْىٌۭ فَهُمْ لَا يَرْجِعُونَ ﴾

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

deaf to the truth so that they cannot hear it and accept it; dumb mute as regards goodness unable to speak of it; and blind to the path of guidance so that they cannot perceive it; they shall not return from error.
