Surah Ar-Rum — Ayah 52 (30:52)
فَإِنَّكَ لَا تُسۡمِعُ ٱلۡمَوۡتَىٰ وَلَا تُسۡمِعُ ٱلصُّمَّ ٱلدُّعَآءَ إِذَا وَلَّوۡاْ مُدۡبِرِينَ ٥٢
English translation (Saheeh International)
So indeed, you will not make the dead hear, nor will you make the deaf hear the call when they turn their backs, retreating.
Brief commentary
So just as you are incapable of making the dead and deaf hear, after they have distanced themselves from you to emphasise their inability to hear you, likewise you cannot guide those who are similar to them if they turn away and do not benefit.
