Immediately after Battle of the Camel, Ali turned to the Levant in the north of the Islamic lands. Muawiyah was the governor of the Levant. He was appointed governor of this region during the rein of Umar and was established there during the time of Uthman. Ali wrote a letter to Mu'awiyah and gave it to Jarir ibn Abdullah Bajli, the former governor of Hamedan, who had been chosen by 'Uthman, to deliver to Muawiyah and take allegiance from him, but Mu'awiyah kept Jarir in that land under various pretexts and During this time he prepared Damascus for battle with Ali.
