Al-Hujurat (The Private Apartments)
Surah 49 · Verse 9
And if two groups from among the believer’s fight, effect reconciliation between them, but if one of them wrongfully oppresses the other then fight against the one which has wrongfully oppressed, till it returns to Allah’s command, then if it returns effect reconciliation between them with justice and act equitably. Allah certainly likes those who are equitable.
Believers should not fight with each other but live as brothers.
