﴿ خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَعَلَىٰ سَمْعِهِمْ ۖ وَعَلَىٰٓ أَبْصَٰرِهِمْ غِشَٰوَةٌۭ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌۭ ﴾

“God; has sealed their hearts and their hearing, and over their eyes is a veil; and awesome suffering awaits them.”

God has set a seal on their hearts impressing on them and making certain that no good enters them; and on their hearing in which He has deposited something so that they cannot profit from the truth they hear; and on their eyes is a covering that is a veil so that they do not see the truth; and for them there will be a mighty chastisement that is intense and everlasting.
