Rashiduin Caliphate April: Amr ibn al-As and Abu Musa al-Ashari conclude the arbitration agreement that ended the Battle of Siffin the previous year, declaring Caliph Ali deposed and declaring Muawiyah as the legitimate Caliph. This badly damages Ali's standing among the Caliphate, and paves the way for the end of the First Fitna. July: Taking advantage of the internal strife befalling Caliph Ali's faction as a result of the arbitration verdict and the Kharijite uprising, Amr ibn al-As enters Egypt with a Syrian army and reclaims the province that he had previously led thirteen years prior, proclaiming himself governor with Muawiyah's agreement. The Egyptian governor appointed by Ali, Muhammad ibn abi Bakr, under pressure due to many of the Muslim soldiers now seeing Muawiyah as the legitimate Caliph, and Amr's high popularity, surrenders the province without bloodshed, depriving Ali of the richest province of the Caliphate, and further undermining his position. Abi Bakr is later killed against Amr's orders, either on Muawiyah's orders or by Syrian soldiers in a summary execution. July 17: The Battle of Nahrawan sees Caliph Ali decisively defeat a Kharijite rebellion, which marks the last fighting of the First Fitna.
