divine wisdom in testing

وَلَقَدْ أَرَيْنَـٰهُ ءَايَـٰتِنَا كُلَّهَا فَكَذَّبَ وَأَبَىٰ

And We certainly showed him [i.e., Pharaoh] Our signs - all of them - but he denied and refused.

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.

وَلَقَدْ فَتَنَّا سُلَيْمَـٰنَ وَأَلْقَيْنَا عَلَىٰ كُرْسِيِّهِۦ جَسَدًا ثُمَّ أَنَابَ

And We certainly tried Solomon and placed on his throne a body; then he returned.

وَءَاتَيْنَـٰهُم مِّنَ ٱلْـَٔايَـٰتِ مَا فِيهِ بَلَـٰٓؤٌا۟ مُّبِينٌ

And We gave them of signs that in which there was a clear trial.
