Siffin
Ali and Muawiyah's armies meet on the Euphrates. After weeks of fighting, copies of the Quran are raised on spears and both sides agree to arbitration.
Ali ibn Abi TalibMuawiyahAmmar ibn Yasir
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 Allah. And if it returns, then make settlement between them in justice and act justly. Indeed, Allah loves those who act justly.
Quran 49:9
