Allāh says in surah al-Taghabun [64]:

مَا أَصَابَ مِن مُّصِيبَةٍ إِلَّا بِإِذْنِ اللَّـهِ ۗ وَمَن يُؤْمِن بِاللَّـهِ يَهْدِ قَلْبَهُ ۚ وَاللَّـهُ بِكُلِّ شَيْءٍ عَلِيمٌ

“No affliction strikes except that it is by Allāh’s permission. And whoever believes in Allāh – He will guide his heart. And Allah is knowing of all things.” [11]

al-haafidh ibn Kathir comments on this ayah by writing:

Whoever is beset with an affliction and recognizes that this affliction is only by Allāh’s decree and predetermination and therefore exercises patience, hopes for a reward and submits to Allāh’s decree – Allāh will guide his heart, recompense him for whatever worldly good he lost with guidance and absolute certainty in his heart, and He might even replace what was taken from him or grant him something better.
