Explaining and illuminating all these things...
Explaining and illuminating all these things, to the extent that they can be touch by the hand and seen by the eye, requires an excellent explanation, a strong heart, and a wide speech. Nothing of my sick body, weak sight, many works, worn out mind, little time, and my bad conditions can help me do that.
May Allah be kind to me and allow me to seize another opportunity, that I may fully explain in this respect, and remove the curtains from this vagueness in order that the truth may appear and the lights may shine. However, there is no escape from ending this word of mine with the pure truth.
Generally speaking, it was incumbent on Imam al-Husayn (a.s) and his companions to revolt against the tyrant of his time (Yazid bin Mu‘awiya) during those circumstances, to the extent that they were killed and the members of Imam al-Husayn’s family, who were the family of Allah’s Apostle, were taken as prisoners of war. This was incumbent on him according to the technique of policy, the rules of victory and prudence regardless of the divine commands and the eternal will.
It was also incumbent on al-Hasan (a.s) during his conditions to make peace with the tyrant of his time (Mu‘awiya bin Abi Sufyan). Had it not been for the peace treaty of al-Hasan and the martyrdom of al-Husayn, Islam would have been destroyed forever.
The efforts of , may Allah bless him and his family, the good, the blessing, the guidance, and the mercy he had brought to people would have been lost, because Abu Sufyan, his bastard (son) Mu‘awiya, and his corrupt grandson Yazid spared no effort to efface Islam and to make the people follow their pre-Islamic beliefs such as worshipping the idols al-Laat and al-Uzza.
Perhaps, the Prophet, may Allah bless him and his family, had referred to this important point through the famous tradition which is as clear as light in correctness. He, (a.s), has said: “Al-Hasan and al-Husayn are two Imams whether they rise or sit down.” Perhaps, he meant that al-Hasan was an Imam through his sitting down (making peace), and that al-Husayn was an Imam through his rising.
Some historians and biographers have related the matter of al-Hasan (a.s) and his making peace with Mu‘awiya. They have dealt with its surface meaning and its simple form without any analyzing, explaining, studying thoroughly, checking out, and without taking into consideration the circumstances of the event, its conditions, principles, and objectives.
