His Piousness and Contentment...
His Piousness and Contentment: Imam Hasan had the worldly possessions at his disposal and could have well enjoyed a luxurious life, but he utilized all of it in the betterment of the condition of the poor. He was so courteous and humble that he never hesitated to sit along with the beggars in the lanes and on the thoroughfares of Medina to reply to some of their religious queries.
Through his cordial attitude and hospitality he never let the poor and the humble feel inferior to him when they visited his abode. Imamate: The demise of the Holy Prophet was followed by an eventful era when the Islamic world (under the false ruling bodies) came in the grip of the fever of expansionism and conquest.
But even under such a revolutionary phase, Imam Hasan kept devoting himself to the sacred mission of peacefully propagating Islam and the teachings of the Holy Prophet along with his great father Imam 'Ali. The martyrdom of Imam Ali on the 21st Ramadan marked the inception of Imam Hasan's Imamate. The majority of Muslims pledged their allegiance to him and finalized the formality of bay'ah (oath of allegiance).
No sooner had he taken the reins of leadership into his hands than he had to meet the challenge of Mu'awiyah, the Governor of Syria, who declared a war against him. In compliance with the Will of Allah and with a view to refrain from causing the massacre of Muslims however, he entered into a piece treaty with Mu'awiyah on terms (though not totally respected and carried out by Mu'awiyah), yet saved Islam and stopped a civil war.
But this peace treaty was never meant as surrender by him of the permanent leadership to Mu'awiyah. It was meant only as an interim transfer of the administration of the Islamic kingdom, subject to the condition that the administration would be surrendered back to Imam Hasan after Mu’awiya’s death and then it would in turn be inherited by Imam Husayn.
Having relieved himself of the administrative responsibilities, Imam Hasan kept the religious leadership with himself and devoted his life to the propagation of Islam and the teachings of the Holy Prophet in Medina. Mu'awiyah's malice against Imam Hasan led him to conspire with the Imam's wife Ja'dah, the daughter of Ash'ath. She was made to give the Imam some poison which affected his liver. Imam Hasan thus succumbed to Mu’awiyah's fatal mischief and attained his martyrdom on 28th Safar 50 AH.
His funeral was attended by Imam Husayn and the members of the Hashimite family.
