Surah Ali 'Imran — Ayah 141 (3:141)
وَلِيُمَحِّصَ ٱللَّهُ ٱلَّذِينَ ءَامَنُواْ وَيَمۡحَقَ ٱلۡكَٰفِرِينَ ١٤١
English translation (Saheeh International)
And that Allāh may purify the believers [through trials] and destroy the disbelievers.
Brief commentary
A part of this wisdom of changing fortunes is the purification of those who have faith from their sins, separating them from the hypocrites, and destroying and removing those who reject the truth.
