Verse 9

وَإِن طَآئِفَتَانِ مِنَ ٱلْمُؤْمِنِينَ ٱقْتَتَلُوا۟ فَأَصْلِحُوا۟ بَيْنَهُمَا فَإِنۢ بَغَتْ إِحْدَىٰهُمَا عَلَى ٱلْأُخْرَىٰ فَقَـٰتِلُوا۟ ٱلَّتِى تَبْغِى حَتَّىٰ تَفِىٓءَ إِلَىٰٓ أَمْرِ ٱللَّهِ فَإِن فَآءَتْ فَأَصْلِحُوا۟ بَيْنَهُمَا بِٱلْعَدْلِ وَأَقْسِطُوٓا۟ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُقْسِطِينَ

And if two groups among the faithful fight, you shall then make peace between them: however, if one of them transgresses against the other, then you shall fight against the one that transgresses until they comply with God’s command. Then, if they comply, make peace between them with justice, and be equitable. Indeed God loves those who are equitable.
