Al-Hujurat 49:10

<h2>Making Peace between Disputing Muslims</h2><p>Allah commands making peace between Muslims that fight each other,</p><p>وَإِن طَآئِفَتَانِ مِنَ الْمُؤْمِنِينَ اقْتَتَلُواْ فَأَصْلِحُواْ بَيْنَهُمَا</p><p>(And if two parties among the believers fall to fighting, then make peace between them both.) Therefore, Allah calls both opposing groups among Muslims, believers, although they are fighting each other. Al-Bukhari and other scholars relied on this Hadith as evidence that committing a sin does not nullify faith, no matter how major the sin is. This creed contradicts the creed of the Khawarij sect and those who accepted their idea, such as the Mu`tazilah sect. Al-Bukhari narrated that Al-Hasan said that Abu Bakrah said that the Messenger of Allah ﷺ gave a speech on the Minbar while Al-Hasan bin `Ali was with him. He was repeatedly looking at Al-Hasan and then at the people; then said,</p><p>«إِنَّ ابْنِي هذَا سَيِّدٌ وَلَعَلَّ اللهَ تَعَالَى أَنْ يُصْلِحَ بِهِ بَيْنَ فِئَتَيْنِ عَظِيمَتَيْنِ مِنَ الْمُسْلِمِين»</p><p>(Verily, this son of mine is a Sayyid (chief or master), and may Allah make peace between two great groups of Muslims through him.) What the Prophet said, occurred. Al-Hasan brought peace between the people of Ash-Sham and `Iraq, after they fought tremendous wars and frightening battles. Allah's statement,</p><p>فَإِن بَغَتْ إِحْدَاهُمَا …

The believers are naught else than brothers. Therefore make peace between your brethren and observe your duty to Allah that haply ye may obtain mercy.

The Believers are but a single Brotherhood: So make peace and reconciliation between your two (contending) brothers; and fear Allah, that ye may receive Mercy.

The believers are nothing else than brothers (in Islamic religion). So make reconciliation between your brothers, and fear Allah, that you may receive mercy.

The believers are brothers, so reconcile between your brothers, and remain conscious of God, so that you may receive mercy.
