Those who criticize say: Imam al-Hassan should not have handed over the affairs and come to term in the situation. He should have fought until he was killed. And in the case of Imam al-Rida, he should not have accepted. He should have resisted and fought as until he got killed, even if he was forced to accept it. We shall now analyze the isse of successoral, which is a very important historical issue, so that the matter is made clear.
The peace of Imam al-Hassan was to an extent discussed previously. We must first investigate the historical view point irrespective of the issue why and how Imam al-Ridaaccepted this offer, to see what the story was. The ‘Abbasid attitude towards the ‘Alawis Ma’mun is the heir to the ‘Abbasid caliphate. Since the first day the ‘Abbasids came to power, their plan was to fight the ‘Alawis and kill them.
The crime the Abbasids committed towards the ‘Alawis when they were in power was not little and even worse in some aspects. However, because of the tragedy of Karbala (where Imam al-Husaynis the one they dealt with) takes place in the time of the Umayyads, the course of events really gets heated. Otherwise, apart from the tragedy of Imam al-Husayn, the disasters they created for the ‘Alawis was nothing less than the tragedy of Karbala and it was at time even worse.
What did Mansur, the second ‘Abbasid Caliph, do with the ‘Alawis, with Imam al-Hassan’s children to whom he gave oath of allegiance? He killed many of them and took them to really hideous prisons. That was where he took a large group of these poor sayyids (the children of the Prophet) to a prison where he gave them no water, no bread and even no permission to go out and go to toilet. This was a form of gradual torture.
When he wanted to kill them, he would say: go and destroy the roof on their heads. Anyone, who came after Mansur, did the same thing. During Ma’mun’s time, five of the Imam’s children rebelled, whose names are mentioned in “Murawwij al-Dhahab” by Mas‘udi and “Kamil” by ibn Athir. During the time of Harun and Ma’mun, seven to eight of the ‘Alawis rebelled. Therefore, hatred and enmity between the ‘Alawis and ‘Abbasids is not a small issue.
The ‘Abbasids did not refrain from any action for gaining power over the caliphate. Even if someone from their own dynasty became their rival, they would not hesitate and immediately killed him.
