While still camping outside Kufah, Muawiyah faced a Kharijite revolt. He sent a cavalry troop against them, but they were beaten back. Mu'awiyah then sent after Hasan, who had already left for Medinah, and commanded him to return and fight against the Kharijites. Hasan, who had reached al-Qadisiyyah, wrote back: "I have abandoned the fight against you, even though it was my legal right, for the sake of peace and reconciliation of the Community. Do you think I shall fight together with you?"
