إِنَّمَا الْمُؤْمِنُونَ إِخْوَةٌ فَأَصْلِحُوا بَيْنَ أَخَوَيْكُمْ ۚ وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُرْحَمُونَ

This verse establishes the fundamental principle of brotherhood among believers, transcending tribal, ethnic, and national boundaries. It declares that faith creates a bond stronger than blood relations. The verse then commands believers to act as peacemakers when conflicts arise between fellow believers, emphasizing the responsibility each Muslim has toward the community. The mention of fearing Allah connects this social responsibility to spiritual consciousness, indicating that maintaining unity among believers is a religious obligation. The promise of mercy for those who fear Allah while working for reconciliation shows that peacemaking is a blessed activity that brings divine reward.
