Surah Al-Anfal · 8:21

وَلَا تَكُونُوا۟ كَٱلَّذِينَ قَالُوا۟ سَمِعْنَا وَهُمْ لَا يَسْمَعُونَ

“O believers! Obey Allah and His Messenger, and do not turn away from him while you hear [his call]. Do not be like those who say, "We hear," but in fact they are not listening. Indeed, the worst of all beings in the Sight of Allah are the [willfully] deaf and dumb, who do not understand. Had Allah known any goodness in them, He would have certainly made them hear. [But] even if He had made them hear, they would have surely turned away heedlessly.”
