171وَمَثَلُ الَّذينَ كَفَروا كَمَثَلِ الَّذي يَنعِقُ بِما لا يَسمَعُ إِلّا دُعاءً وَنِداءً ۚ صُمٌّ بُكمٌ عُميٌ فَهُم لا يَعقِلونَMuhammad SarwarPreaching to unbelievers is like talking to someone who cannot hear anything except yells and shouts. They are deaf, dumb, and blind; they have no understanding.
