Wisdom in testing and trials

وَلَمَّا فَتَحُوا۟ مَتَـٰعَهُمْ وَجَدُوا۟ بِضَـٰعَتَهُمْ رُدَّتْ إِلَيْهِمْ ۖ قَالُوا۟ يَـٰٓأَبَانَا مَا نَبْغِى ۖ هَـٰذِهِۦ بِضَـٰعَتُنَا رُدَّتْ إِلَيْنَا ۖ وَنَمِيرُ أَهْلَنَا وَنَحْفَظُ أَخَانَا وَنَزْدَادُ كَيْلَ بَعِيرٍ ۖ ذَٰلِكَ كَيْلٌ يَسِيرٌ

And when they opened their baggage, they found their merchandise returned to them. They said, "O our father, what [more] could we desire? This is our merchandise returned to us. And we will obtain supplies [i.e., food] for our family and protect our brother and obtain an increase of a camel's load; that is an easy measurement."

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.
