heart sealing

مَن يُضْلِلِ ٱللَّهُ فَلَا هَادِىَ لَهُۥ ۚ وَيَذَرُهُمْ فِى طُغْيَـٰنِهِمْ يَعْمَهُونَ

Whoever Allāh sends astray - there is no guide for him. And He leaves them in their transgression, wandering blindly.

ٱلَّذِينَ يُجَـٰدِلُونَ فِىٓ ءَايَـٰتِ ٱللَّهِ بِغَيْرِ سُلْطَـٰنٍ أَتَىٰهُمْ ۖ كَبُرَ مَقْتًا عِندَ ٱللَّهِ وَعِندَ ٱلَّذِينَ ءَامَنُوا۟ ۚ كَذَٰلِكَ يَطْبَعُ ٱللَّهُ عَلَىٰ كُلِّ قَلْبِ مُتَكَبِّرٍ جَبَّارٍ

Those who dispute concerning the signs of Allāh without an authority having come to them - great is hatred [of them] in the sight of Allāh and in the sight of those who have believed. Thus does Allāh seal over every heart [belonging to] an arrogant tyrant.
