Surah Ar-Rum, ayah 52

فَإِنَّكَ لَا تُسۡمِعُ ٱلۡمَوۡتَىٰ وَلَا تُسۡمِعُ ٱلصُّمَّ ٱلدُّعَآءَ إِذَا وَلَّوۡاْ مُدۡبِرِينَ ٥٢

Fa innaka lā tusmi'ul-mawtā walā tusmi'us-summad-du'ā'a idhā wallaw mudbirīn

So indeed, you will not make the dead hear, nor will you make the deaf hear the call when they turn their backs, retreating.
