Surah Al-Hujuraat Verse 9

وَإِن طَائِفَتَانِ مِنَ الْمُؤْمِنِينَ اقْتَتَلُوا فَأَصْلِحُوا بَيْنَهُمَا ۖ فَإِن بَغَتْ إِحْدَاهُمَا عَلَى الْأُخْرَىٰ فَقَاتِلُوا الَّتِي تَبْغِي حَتَّىٰ تَفِيءَ إِلَىٰ أَمْرِ اللَّهِ ۚ فَإِن فَاءَتْ فَأَصْلِحُوا بَيْنَهُمَا بِالْعَدْلِ وَأَقْسِطُوا ۖ إِنَّ اللَّهَ يُحِبُّ الْمُقْسِطِينَ

Wa in taaa'ifataani minal mu'mineenaq tataloo faaslihoo bainahumaa fa-im baghat ih daahumaa 'alal ukhraa faqaatilul latee tabhee hattaa tafeee'a ilaaa amril laah; fa-in faaa't fa aslihoo bainahumaa bil'adli wa aqsitoo innal laaha yuhibbul muqsiteen

Translation / The Meaning

And if two factions among the believers should fight, then make settlement between the two. But if one of them oppresses the other, then fight against the one that oppresses until it returns to the ordinance of Allah. And if it returns, then make settlement between them in justice and act justly. Indeed, Allah loves those who act justly.
