As soon as Muawiyah took over the reins of government...
As soon as Muawiyah took over the reins of government, the wealth of Bani Umayyah began to increase rapidly till finally, Muawiyah became the ruler of all the Islamic lands. We should know that as the Bani Umayyah gained wealth and strength, the Bani Hashim became further away from power and rulership. Due to the above reasons, the Bani Hashim were out of the common populace and their apparent status was no more.
Then even though they got rulership during the Caliphate of Ali (a.s.) they could not regain their lost position. Even after gaining the Caliphate, His Eminence, Ali (a.s.) could not dethrone Muawiyah. Ali (a.s.) continued to confront the Bani Umayyah but even after all the turmoil, Muawiyah continued to remain in power. The limited and temporary status of Bani Hashim ended with the martyrdom of Ali (a.s.).
Though Imam Hasan (a.s.) was the successor of his respected father, within a period of six months he had to forgo rulership due to Muawiyah’s onslaught. Here we do not debate whether Ali (a.s.) was on the right or Muawiyah or whether the forced abdication of Imam Hasan (a.s.) by Muawiyah was justified or not.
Our aim in presenting these historical facts is only to show the terrible calamities that befell Muhammad’s Progeny after the passing away of the Prophet, due to which their status fell in the view of public, day by day and this finally culminated into the incident known as the tragedy of Karbala’. Anyway, after the abdication of Caliphate, Imam Hasan (a.s.) became a pensioner of Muawiyah. This was by no means a great insult of Muhammad’s Progeny.
At that time, all the Islamic lands were under the domination of Bani Umayyah. Muawiyah was not the chief of Bani Umayyah and ruler of Shaam alone. Being the Caliph of the time, his power extended to even Mecca and Medina. However, there lived in Medina, Imam Hasan, Imam Husayn (a.s.) and other Bani Hashim. But none of the Bani Hashim had any kind of rulership. The command and the monetary wealth of the government were all in the hands of Muawiyah. In spite of this, Muawiyah was not satisfied.
At last, the martyrdom of Imam Hasan (a.s.) pleased the heart of the Caliph.[^2] But that Imam Husayn (a.s.) was yet alive was not a lesser worry to Muawiyah. Muawiyah knew that Imam Husayn (a.s.) had inherited the valor of his father. So to remain careless of him would be against reason. Therefore, he used to tell his son: “Do not consider your throne safe.
