The Quran

179

وَلَقَد ذَرَأنا لِجَهَنَّمَ كَثيرًا مِنَ الجِنِّ وَالإِنسِ ۖ لَهُم قُلوبٌ لا يَفقَهونَ بِها وَلَهُم أَعيُنٌ لا يُبصِرونَ بِها وَلَهُم آذانٌ لا يَسمَعونَ بِها ۚ أُولٰئِكَ كَالأَنعامِ بَل هُم أَضَلُّ ۚ أُولٰئِكَ هُمُ الغافِلونَ

Muhammad Asad

And most certainly have We destined for hell many of the invisible beings¹ and men who have hearts with which they fail to grasp the truth, and eyes with which they fail to see, and ears with which they fail to hear. They are like cattle - nay, they are even less conscious of the right way:² it is they, they who are the [truly] heedless!

See Appendix 111.
Lit.; "they are farther astray" - inasmuch as animals follow only their instincts and natural needs and are not conscious of the possibility or necessity of a moral choice.
