Divine justice and consequences of disbelief

خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَعَلَىٰ سَمْعِهِمْ ۖ وَعَلَىٰٓ أَبْصَـٰرِهِمْ غِشَـٰوَةٌ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌ

Allāh has set a seal upon their hearts and upon their hearing, and over their vision is a veil. And for them is a great punishment.

فِى قُلُوبِهِم مَّرَضٌ فَزَادَهُمُ ٱللَّهُ مَرَضًا ۖ وَلَهُمْ عَذَابٌ أَلِيمٌۢ بِمَا كَانُوا۟ يَكْذِبُونَ

In their hearts is disease, so Allāh has increased their disease; and for them is a painful punishment because they [habitually] used to lie.

وَجَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِىٓ ءَاذَانِهِمْ وَقْرًا ۚ وَإِذَا ذَكَرْتَ رَبَّكَ فِى ٱلْقُرْءَانِ وَحْدَهُۥ وَلَّوْا۟ عَلَىٰٓ أَدْبَـٰرِهِمْ نُفُورًا

And We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And when you mention your Lord alone in the Qur’ān, they turn back in aversion.

وَقَالَ فِرْعَوْنُ يَـٰٓأَيُّهَا ٱلْمَلَأُ مَا عَلِمْتُ لَكُم مِّنْ إِلَـٰهٍ غَيْرِى فَأَوْقِدْ لِى يَـٰهَـٰمَـٰنُ عَلَى ٱلطِّينِ فَٱجْعَل لِّى صَرْحًا لَّعَلِّىٓ أَطَّلِعُ إِلَىٰٓ إِلَـٰهِ مُوسَىٰ وَإِنِّى لَأَظُنُّهُۥ مِنَ ٱلْكَـٰذِبِينَ

And Pharaoh said, "O eminent ones, I have not known you to have a god other than me. Then ignite for me, O Hāmān, [a fire] upon the clay and make for me a tower that I may look at the God of Moses. And indeed, I do think he is among the liars."
