Trade markets became active in it.
Trade markets became active in it. Scientific studies became bright in it. Gardens and villages were built around it. Glorious history, arts, sciences lasted in it for a long time. Shi'ism (tashayu) for Imam 'Ali and his sons, peace be on them, prevailed Kufa under the Hashimite ruling. This phenomenon has been in it since that time. Because of the mixed groups who inhabited the new city, other hostile desires appeared there beside Shi'ism.
After a short time, such hostile motives became the reason for creating historical events in Kufa. The pledge of allegiance to al-Hasan, peace be on him, occurred when Kufa pledged allegiance to him. Then all the people there agreed on his nomination though they rarely agreed on a certain idea. Throughout his life in this city, al-Hasan, peace be on him, showed the noble qualities which the family of Muhammad, may Allah bless him and his family, inherited.
Those noble qualities were: goodness, good manners, noble feelings, gentle traits, wide patience, excellent mind, knowledge, religious devotion, worship, and the like. So the hearts of the people inclined towards him. The Pulpit of the succession, though sad for the late Imam ('Ali), smiled at the Prophetic qualities inherited by its new Successor. For he was the best person in piety, refraining from the life in this world, and collecting all good traits.
For this reason, he (al-Hasan) was a unique figure. Thus all different persons agreed on him willingly. Moreover, all the elements of leadership necessary for the leader of a nation or the Imam of people gathered in al-Hasan. The festivals of the pledge of allegiance to al-Hasan, peace be on him, in Kufa ended in the hoped manner. They resulted in strength, activity, and mobilization.
However, fate has rules that do not occur according to the measures of minds, nor do they occur according to the desires of selves. So the political atmosphere in the city of (Kufa), that celebrated the appointment of the Successor for the first time in its history, was still stagnant, clouded, and mingled with much suspicious disturbance. That was what Kufa suffered from because of the effects of the violent battles that happened in the neighboring places, namely in Basrah, Nahrwan, and Siffin.
In Kufa, at that time, there were many supporters for the martyrs and victims of these battles from both parties. Those supporters were very eager to avenge the blood of their martyrs. So they spared no effort to carry out their purposes.
