No kind of calamity can occur, except by the leave of Allah: and if any one believes in Allah, (Allah) guides his heart (aright): for Allah knows all things. At-Taghabun 64:11 ⧉
Tafsir:
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.
