عَوِّدْ أُذُنَكَ حُسْنَ الِاسْتِمَاعِ وَ لَا تُصْغِ إِلَى مَا لَا يَزِيدُ فِي صلَاحِكَ اسْتِمَاعُهُ فَإِنَّ ذَلِكَ يُصْدِئُ الْقُلُوبَ وَ يُوجِبُ الْمَذَامَّ .
Imam Ali (as):
Accustom your ears to listening attentively, and do not listen to anything that does not benefit your progress, for it contaminates the heart and brings about reproach.
