Permission ˹to fight˺ has been given to those who are being fought, because they were wronged. And indeed, Allah is competent to give them victory.
أُذِنَ لِلَّذِينَ يُقَاتَلُونَ بِأَنَّهُمْ ظُلِمُوا ۚ وَإِنَّ اللَّهَ عَلَىٰ نَصْرِهِمْ لَقَدِيرٌ
[Machine] "He used to recite it: "Permission [to fight] has been given to those who are being fought, because they were wronged. And indeed, Allah is competent to give them victory." [Quran 22:39] He said, "This is the first verse revealed concerning fighting."
أَنَّهُ كَانَ يَقْرَؤُهَا {أُذِنَ لِلَّذِينَ يُقَاتَلُونَ بِأَنَّهُمْ ظُلِمُوا وَإِنَّ اللَّهَ عَلَى نَصْرِهِمْ لَقَدِيرٌ} [الحج 39] قَالَ «هِيَ أَوَّلُ آيَةٍ نَزَلَتْ فِي الْقِتَالِ»
