﴿ إِنَّمَا ٱلْمُؤْمِنُونَ إِخْوَةٌۭ فَأَصْلِحُوا۟ بَيْنَ أَخَوَيْكُمْ ۚ وَٱتَّقُوا۟ ٱللَّهَ لَعَلَّكُمْ تُرْحَمُونَ ﴾

“All believers are but brethren. Hence, [when­ever they are at odds,] make peace between your two brethren, and remain conscious of God, so that you might be graced with His mercy.”

The believers are indeed brothers in religion. Therefore always make peace between your brethren when they fall into dispute with one another a variant reading for the dual form akhawaykum ‘your two brethren’ has ikhwatakum ‘your brothers’ and fear God so that perhaps you might receive mercy.
