اُذِنَ لِلَّذِيۡنَ يُقٰتَلُوۡنَ بِاَنَّهُمۡ ظُلِمُوۡاؕ وَاِنَّ اللّٰهَ عَلٰى نَـصۡرِهِمۡ لَـقَدِيۡرُۙ
Permission (to fight against mischief, disruption and oppression) is granted to those against whom (unjust) war is waged, because they were oppressed and Allah is doubtlessly All-Powerful to help them (the oppressed).
