وَلَقَدْ ذَرَأْنَا لِجَهَنَّمَ كَثِيرًۭا مِّنَ ٱلْجِنِّ وَٱلْإِنسِ ۖ لَهُمْ قُلُوبٌۭ لَّا يَفْقَهُونَ بِهَا وَلَهُمْ أَعْيُنٌۭ لَّا يُبْصِرُونَ بِهَا وَلَهُمْ ءَاذَانٌۭ لَّا يَسْمَعُونَ بِهَآ ۚ أُو۟لَٰٓئِكَ كَٱلْأَنْعَٰمِ بَلْ هُمْ أَضَلُّ ۚ أُو۟لَٰٓئِكَ هُمُ ٱلْغَٰفِلُونَ
Already have We urged unto hell many of the jinn and humankind, having hearts wherewith they understand not, and having eyes wherewith they see not, and having ears wherewith they hear not. These are as the cattle - nay, but they are worse! These are the neglectful.
Surah Al-A'raaf(7:179)
