Ar-Rum 52

فَإِنَّكَ لَا تُسْمِعُ ٱلْمَوْتَىٰ وَلَا تُسْمِعُ ٱلصُّمَّ ٱلدُّعَآءَ إِذَا وَلَّوْا۟ مُدْبِرِينَ

fa-innaka lā tus'miʿu l-mawtā walā tus'miʿu l-ṣuma l-duʿāa idhā wallaw mud'birīna

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