He never withheld his opinion about what was helpful or in the interest of Islam and the Muslims, and he often said: I was afraid lest I should not help Islam and the Muslims, and that they would fail. He said and did nothing against the position, power and authority of the Khulafa', but kept himself to his house and remained silent, despite the fact that he saw what they were doing. He acted thus for the sake of Islamic interests, up to the point where he was famous for his admirable qualities.

The second khalifah' Umar ibn Khattab, said many times: "I would never encounter a difficulty without Abu 'I-Hasan being there to contribute to its solution, "And" if it were not for 'Ali, 'Umar (himself) would never perished." History cannot forget the way Imam Hasan (A.S) dealt with Mu'awiyah.

He made peace with him, because he realized that if he continued to fight, the light of the Qur'an and just government would be extinguished, and moreover the name of Islam would vanish for all time, the Divine shari'ah would be lost and the Imams that were to come would be obliterated. So he chose to protect the edifice of Islam and its name. For this reason, he made peace with Mu'awiyah, who was a resolute enemy of the religion and Muslims and who hated Imam Hasan and his followers.

He knew that Mu'awiyah would deal unjustly with him and his companions, and, although he could have counted on his family and followers to fight for their sights and defend themselves, he believed that the highest interests of Islam were above all these things and more important than them.

It was for the same reason that the third Imam, Husayn, the Holy Martyr, rose up against the Banu Umayyah; for he realized that if they continued in their vicious ways without anyone taking arms against them and proclaiming their wicked intentions, they would eradicate Islam and its glory, so as to expose their evil plans against the Prophet's religion. Naturally, events turned our as had been predicated.

If it had not been for his holy campaign, Islam would have been recorded as a religion of the past, and it would have been though a false religion. In completing his holy campaign, following through and pursuing his sacred aim against iniquity and oppression, the Shi'ah revive and remember the tragedy at Karbala every year and it various ways, as the Imams have commanded.
