Sura al-Baqara 2:226

لِّلَّذِينَ يُؤْلُونَ مِن نِّسَآئِهِمْ تَرَبُّصُ أَرْبَعَةِ أَشْهُرٍ فَإِن فَآءُو فَإِنَّ ٱللَّـهَ غَفُورٌ رَّحِيمٌ

li-lladhīna yuʾlūna min nisāʾihim tarabbuṣu arbaʿati ashhurin fa-in fāʾū fa-inna allāha ghafūrun raḥīmun

For those who take an oath for abstention from their wives, a waiting for four months is ordained; if then they return, Allah is Oft-forgiving, Most Merciful.

Sura al-Ḥujurāt 49:9

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

wa-in ṭāʾifatāni mina l-muʾminīna iqtatalū fa-aṣliḥū baynahumā fa-in baghat iḥdāhumā ʿalā l-ukhrā fa-qātilū allatī tabghī ḥattā tafīʾa ila amri allāhi fa-in fāʾat fa-aṣliḥū baynahumā bil-ʿadli wa-aqsiṭū inna allāha yuḥibbu l-muqsiṭīna

If two parties among the Believers fall into a quarrel, make ye peace between them: but if one of them transgresses beyond bounds against the other, then fight ye (all) against the one that transgresses until it complies with the command of Allah; but if it complies, then make peace between them with justice, and be fair: for Allah loves those who are fair (and just).
