﴿ إِنَّ ٱلَّذِينَ يَكْتُمُونَ مَآ أَنزَلَ ٱللَّهُ مِنَ ٱلْكِتَٰبِ وَيَشْتَرُونَ بِهِۦ ثَمَنًۭا قَلِيلًا ۙ أُو۟لَٰٓئِكَ مَا يَأْكُلُونَ فِى بُطُونِهِمْ إِلَّا ٱلنَّارَ وَلَا يُكَلِّمُهُمُ ٱللَّهُ يَوْمَ ٱلْقِيَٰمَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ ﴾

“VERILY, as for those who suppress aught of the revelation which God has bestowed from on high, and barter it away for a trifling gain - they but fill their bellies with fire. And God will not speak unto them on the Day of Resurrection, nor will He cleanse them [of their sins]; and grievous suffering awaits them.”
