Consequence of Rejecting Truth

أَفَأَمِنُوا۟ مَكْرَ ٱللَّهِ ۚ فَلَا يَأْمَنُ مَكْرَ ٱللَّهِ إِلَّا ٱلْقَوْمُ ٱلْخَـٰسِرُونَ

Then, did they feel secure from the plan of Allāh? But no one feels secure from the plan of Allāh except the losing people.

لِّيَجْعَلَ مَا يُلْقِى ٱلشَّيْطَـٰنُ فِتْنَةً لِّلَّذِينَ فِى قُلُوبِهِم مَّرَضٌ وَٱلْقَاسِيَةِ قُلُوبُهُمْ ۗ وَإِنَّ ٱلظَّـٰلِمِينَ لَفِى شِقَاقٍۭ بَعِيدٍ

[That is] so He may make what Satan throws in [i.e., asserts] a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension.
