Some of the troops, taking this as a sign that Al-Hasan was preparing to give up battle, rebelled against him, and looted his tent, seizing even the prayer rug from underneath him. Hasan shouted for his horse and rode off surrounded by his partisans who kept back those who were trying to reach him. While they were passing by Sabat, however, al-Jarrah ibn Sinan, a Kharijite, managed to ambush Hasan and wounded him in the thigh with a dagger, while he was shouting: "God is the Greatest! You have become a "Kafir" (, Infidel) like your father before you." Abd Allah ibn al-Hisl jumped upon him, and as others joined in, al-Jarrah was overpowered, and he died. Hasan was taken to Al-Mada'in where he was cared for by his governor, Sa'd ibn Mas'ud al-Thaqafi The news of this attack, having been spread by Mu‘awiyah, further demoralised the already discouraged army of Al-Hasan, and led to extensive desertion from his troops.
