49 : 9
وَإِن طَآئِفَتَانِ مِنَ ٱلۡمُؤۡمِنِينَ ٱقۡتَتَلُواْ فَأَصۡلِحُواْ بَيۡنَهُمَاۖ فَإِنۢ بَغَتۡ إِحۡدَىٰهُمَا عَلَى ٱلۡأُخۡرَىٰ فَقَٰتِلُواْ ٱلَّتِي تَبۡغِي حَتَّىٰ تَفِيٓءَ إِلَىٰٓ أَمۡرِ ٱللَّهِۚ فَإِن فَآءَتۡ فَأَصۡلِحُواْ بَيۡنَهُمَا بِٱلۡعَدۡلِ وَأَقۡسِطُوٓاْۖ إِنَّ ٱللَّهَ يُحِبُّ ٱلۡمُقۡسِطِينَ
If two groups of the believers fight one another, make peace between them. If one of them transgresses against the other, fight against the transgressing group until they submit to the rule of Allah. Then if they submit, make peace between them with fairness, and be just, for Allah loves those who are just.
