And surely, We will fill Hell with most of the Jinns and mankind, for them have hearts with which they don't understand the aim of life, for them have eyes with which they don't see the Insight, for them have ears with which they don't hear It. Such are just like livestock, nay, they are the most strayed, such are heedless.
Adhikr is the Insight mentioned in this verse. The aimless Arabic Quran reading Fujjar hide and reject Adhikr. They don't utilize their intelligence to understand the aim of life. Even though they have faculties of sight, hearing, and intelligence, they don't read or hear or think about Lord’s Book Adhikr as explained in verse 6: 104. The Fujjar are denoted as the worthless people in verse 25: 18. They are denoted as the worst among the thousand communities of Lord's creatures who are deaf and dumb towards Adhikr as explained in verses 8: 22 and 25: 34. Since Fujjar have been killed by the Lord as explained in verse 4: 41, nobody can remind them with Adhikr. Lord has sealed the hearts, ears, and sight of Fujjar, thus they have become the heedless and losers in the Hereafter as explained in verses 16: 108-109. See explanation 4: 150 -151 and 9: 67-68.
