﴿ مَآ أَصَابَ مِن مُّصِيبَةٍ إِلَّا بِإِذْنِ ٱللَّهِ ۗ وَمَن يُؤْمِنۢ بِٱللَّهِ يَهْدِ قَلْبَهُۥ ۚ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌۭ ﴾

“NO CALAMITY can ever befall [man] unless it be by God's leave: hence, whoever believes in God guides his [own] heart [towards this truth]; and God has full knowledge of everything.”

No trouble arrives of its own accord. Every tribulation comes from God, and it afflicts man so that, through it, he should receive guidance. Trouble softens a man’s heart and jolts him out of his moral slumber. Trouble prods and sharpens a man’s mind. If he refrains from negative reaction, then trouble will become the best Divine instruction for him.
