With the departure of Abu Musa Ashari from Kufa, a pro-Ali government was set up in Kufa. The new Government proclaimed their full support to Ali. The new Governor addressed the people of Kufa in the mosque, and exhorted them to enroll themselves in the ranks of Ali and strengthen his hands to enable him fight for the truth. Imam Hasan also addressed the people. He said: "Ali has sent me to you with his message of goodwill for you. Of all the people in the commonwealth he has the greatest regard for you. He intends to make Kufa the capital of the Muslim Empire. This is a great honor, but Kufa deserves it. You are the people who can distinguish truth from falsehood. The way in which you have risen in the cause of Ali is a positive proof of your love for the truth. Your Caliph needs your assistance. It is both in your interest and duty incumbent on you to help him. Can you give any reason for refusing his help? Is there any one who can reasonably accuse him of having shown any covetous inclinations, or withholding or perverting justice? Can any one amongst you say that he thrust himself into the Caliphate or that he proved himself unworthy of this dignity in any way? Beware of those rebels who pretend to have taken up arms to avenge the murder of Othman. O ye people of Kufa, the avenging of the murder of Othman is merely a pretext to dethrone the Caliph Ali. Ali was elected as the Caliph unanimously by the people of Madina. Talha and Zubair who now lead the rebels took the oath of allegiance to him. Indeed they were the first to support him. Now they are the first to forswear him. Therefore O ye the people of Kufa, it is incumbent on you to come and do what is good and forbid what is evil. Islam expects you to do your duty, and your duty lies in supporting your Caliph."
The magnetic personality of Imam Hasan, and his inspiring address won the hearts of the people of Kufa, and they declared that they would stand by their Caliph through thick and thin. The people began to flock to the standard of Imam Hasan in large numbers, and enrolled themselves as volunteers. Within a week, a force ten thousand strong was raised from Kufa to support Ali.
