﴿ 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 naught else than brothers) in religion. (Therefore make peace between your brethren) by means of the Book of Allah (and observe your duty to Allah) and fear Allah regarding that which He commands you regarding making peace (that haply ye may obtain mercy) and not be punished.
