Surah Al-Anfal — Ayah 25 (8:25)
وَٱتَّقُواْ فِتۡنَةٗ لَّا تُصِيبَنَّ ٱلَّذِينَ ظَلَمُواْ مِنكُمۡ خَآصَّةٗۖ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ شَدِيدُ ٱلۡعِقَابِ ٢٥
English translation (Saheeh International)
And fear a trial1 which will not strike those who have wronged among you exclusively, and know that Allāh is severe in penalty.
- - i.e., an affliction or punishment during life upon this earth. When corruption spreads among a people, its consequences will affect everyone.
Brief commentary
Beware of suffering that does not only reach those who do wrong among you, but reaches you and others as well. This is when disobedience becomes widespread and is not prevented. Be sure that Allah is strong with the punishment for those who go against Him, so beware of opposing Him.
