Al-Hujurat 49:9 وان طايفتان من المومنين اقتتلوا فاصلحوا بينهما فان بغت احداهما على الاخرى فقاتلوا التي تبغي حتى تفيء الى امر الله فان فاءت فاصلحوا بينهما بالعدل واقسطوا ان الله يحب المقسطين ٩

And if two parties of believers fall to fighting, then make peace between them. And if one party of them doeth wrong to the other, fight ye that which doeth wrong till it return unto the ordinance of Allah; then, if it return, make peace between them justly, and act equitably. Lo! Allah loveth the equitable.

And if two factions among the believers should fight, then make settlement between the two. But if one of them oppresses the other, then fight against the one that oppresses until it returns to the ordinance of Allāh. And if it returns, then make settlement between them in justice and act justly. Indeed, Allāh loves those who act justly.

If two parties among the Believers fall into a quarrel, make ye peace between them: but if one of them transgresses beyond bounds against the other, then fight ye (all) against the one that transgresses until it complies with the command of Allah; but if it complies, then make peace between them with justice, and be fair: for Allah loves those who are fair (and just).
