Divine providence and testing

أَيَوَدُّ أَحَدُكُمْ أَن تَكُونَ لَهُۥ جَنَّةٌ مِّن نَّخِيلٍ وَأَعْنَابٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ لَهُۥ فِيهَا مِن كُلِّ ٱلثَّمَرَٰتِ وَأَصَابَهُ ٱلْكِبَرُ وَلَهُۥ ذُرِّيَّةٌ ضُعَفَآءُ فَأَصَابَهَآ إِعْصَارٌ فِيهِ نَارٌ فَٱحْتَرَقَتْ ۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمُ ٱلْـَٔايَـٰتِ لَعَلَّكُمْ تَتَفَكَّرُونَ

Would one of you like to have a garden of palm trees and grapevines underneath which rivers flow in which he has from every fruit? But he is afflicted with old age and has weak [i.e., immature] offspring, and it is hit by a whirlwind containing fire and is burned. Thus does Allāh make clear to you [His] verses that you might give thought.

فَلَمَّا رَجَعُوٓا۟ إِلَىٰٓ أَبِيهِمْ قَالُوا۟ يَـٰٓأَبَانَا مُنِعَ مِنَّا ٱلْكَيْلُ فَأَرْسِلْ مَعَنَآ أَخَانَا نَكْتَلْ وَإِنَّا لَهُۥ لَحَـٰفِظُونَ

So when they returned to their father, they said, "O our father, [further] measure has been denied to us, so send with us our brother [that] we will be given measure. And indeed, we will be his guardians."
