Al Hajj, 39 Ayah
22:39
أُذِنَ لِلَّذِينَ يُقَٰتَلُونَ بِأَنَّهُمۡ ظُلِمُواْۚ وَإِنَّ ٱللَّهَ عَلَىٰ نَصۡرِهِمۡ لَقَدِيرٌ ٣٩
'Udhina Lilladhīna Yuqātalūna Bi'annahum Žulimū ۚ Wa 'Inna Al-Laha `Alá Naşrihim Laqadīrun
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.
