Surah An Naml Tafseer

إِنَّكَ لَا تُسْمِعُ الْمَوْتَى

Verily, you cannot make the dead to hear,

meaning, you cannot cause them to hear anything that will benefit them. The same applies to those over whose hearts is a veil and in whose ears is deafness of disbelief.

Allah says:

وَلَا تُسْمِعُ الصُّمَّ الدُّعَاء إِذَا وَلَّوْا مُدْبِرِينَ

وَمَا أَنتَ بِهَادِي الْعُمْيِ عَن ضَلَلَتِهِمْ إِن تُسْمِعُ إِلاَّ مَن يُوْمِنُ بِأيَاتِنَا فَهُم مُّسْلِمُونَ
