Al-Anbiya' - 21:45

قُلْ إِنَّمَا أُنذِرُكُم بِالْوَحْيِ وَلَا يَسْمَعُ الصُّمُّ الدُّعَاء إِذَا مَا يُنذَرُونَ
[21:45]
Say: I warn you only by revelation; and the deaf do not hear the call whenever they are warned.
Say, "I do but warn you according to revelation": But the deaf will not hear the call, (even) when they are warned!
Say (O Muhammad, unto mankind): I warn you only by the Inspiration. But the deaf hear not the call when they are warned.
