Indeed, al-Hasan did as his father did.

Indeed, al-Hasan did as his father did. He treated the conditions and the enemies as his father did. It is as if that al-Hasan and his father, the Commander of the faithful, peace be on him, lived during the same time in Kufa. War was an inevitable necessity during the time of the late father (i.e., Imam 'Ali), peace be on him. Thus it was also an inevitable necessity during the time of the son (i.e., al Hasan) who assumed the succession. It was necessary for al-Hasan to adorn the new succession.
