Surah Al-Anbiya' (The Prophets), Verse 45

قُلْ اِنَّمَاۤ اُنْذِرُكُمْ بِالْوَحْیِ وَلَا یَسْمَعُ الصُّمُّ الدُّعَآءَ اِذَا مَا یُنْذَرُوْنَ ۟

Qul innamaaa unzirukum bilwahyi; wa laa yasma'us summud du'aaa 'a izaa maa yunzaroon

“Say, "I do but warn you according to revelation": But the deaf will not hear the call, (even) when they are warned!”
