﴿ ۞ إِنَّ شَرَّ ٱلدَّوَآبِّ عِندَ ٱللَّهِ ٱلصُّمُّ ٱلْبُكْمُ ٱلَّذِينَ لَا يَعْقِلُونَ ﴾

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

It was also revealed about these: (Lo! the worst of beasts) created beings and creatures (in Allah's sight are the deaf) to the Truth, (the dumb) about the Truth, (who have no sense) who do not understand Allah's command and His divine Oneness.
