Al-Anfal 22

۞ إِنَّ شَرَّ ٱلدَّوَآبِّ عِندَ ٱللَّهِ ٱلصُّمُّ ٱلْبُكْمُ ٱلَّذِينَ لَا يَعْقِلُونَ

inna sharra l-dawābi ʿinda l-lahi l-ṣumu l-buk'mu alladhīna lā yaʿqilūna

Indeed, the worst of living creatures in the sight of Allāh are the deaf and dumb who do not use reason [i.e., the disbelievers].
