Surah Al-Baqarah — Ayah 171 (2:171)
وَمَثَلُ ٱلَّذِينَ كَفَرُواْ كَمَثَلِ ٱلَّذِي يَنۡعِقُ بِمَا لَا يَسۡمَعُ إِلَّا دُعَآءٗ وَنِدَآءٗۚ صُمُّۢ بُكۡمٌ عُمۡيٞ فَهُمۡ لَا يَعۡقِلُونَ ١٧١
English translation (Saheeh International)
The example of those who disbelieve is like that of one who shouts at what hears nothing but calls and cries [i.e., cattle or sheep] - deaf, dumb and blind, so they do not understand.
Brief commentary
The example of those who disbelieve and stubbornly follow the path of their fathers is like the example of the shepherd who shouts, calling to his animals that hear his voice, but do not understand what he says. They are deaf to hearing the truth so that it will benefit them, dumb as they are unable to speak about the truth, and blind to seeing it, and because of this they do not understand the guidance which you call them to.
