heart sealing (tabʿ)

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.
