وَمَثَلُ ٱلَّذِينَ كَفَرُوا۟ كَمَثَلِ ٱلَّذِى يَنْعِقُ بِمَا لَا يَسْمَعُ إِلَّا دُعَآءً وَنِدَآءً ۚ صُمٌّۢ بُكْمٌ عُمْىٌ فَهُمْ لَا يَعْقِلُونَ

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.

Al-Baqarah 171

وَلَقَدْ ذَرَأْنَا لِجَهَنَّمَ كَثِيرًا مِّنَ ٱلْجِنِّ وَٱلْإِنسِ ۖ لَهُمْ قُلُوبٌ لَّا يَفْقَهُونَ بِهَا وَلَهُمْ أَعْيُنٌ لَّا يُبْصِرُونَ بِهَا وَلَهُمْ ءَاذَانٌ لَّا يَسْمَعُونَ بِهَآ ۚ أُو۟لَـٰٓئِكَ كَٱلْأَنْعَـٰمِ بَلْ هُمْ أَضَلُّ ۚ أُو۟لَـٰٓئِكَ هُمُ ٱلْغَـٰفِلُونَ

And We have certainly created for Hell many of the jinn and mankind. They have hearts with which they do not understand, they have eyes with which they do not see, and they have ears with which they do not hear. Those are like livestock; rather, they are more astray.1 It is they who are the heedless.

Al-A'raf 179

وَإِذَا مَآ أُنزِلَتْ سُورَةٌ نَّظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَىٰكُم مِّنْ أَحَدٍ ثُمَّ ٱنصَرَفُوا۟ ۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ

And whenever a sūrah is revealed, they look at each other, [as if saying], "Does anyone see you?" and then they dismiss themselves. Allāh has dismissed their hearts because they are a people who do not understand.

At-Tawbah 127

وَمِنْهُم مَّن يَنظُرُ إِلَيْكَ ۚ أَفَأَنتَ تَهْدِى ٱلْعُمْىَ وَلَوْ كَانُوا۟ لَا يُبْصِرُونَ

And among them are those who look at you. But can you guide the blind although they will not [attempt to] see?

Yunus 43

۞ أَفَمَن يَعْلَمُ أَنَّمَآ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ ٱلْحَقُّ كَمَنْ هُوَ أَعْمَىٰٓ ۚ إِنَّمَا يَتَذَكَّرُ أُو۟لُوا۟ ٱلْأَلْبَـٰبِ

Then is he who knows that what has been revealed to you from your Lord is the truth like one who is blind? They will only be reminded who are people of understanding -

Ar-Ra'd 19
