He saw the Imam standing near the grave of the Prophet...
He saw the Imam standing near the grave of the Prophet weeping and complaining to the Prophet about the III-treatment that Imam (A.S) and the other members of the Prophet's family had received from the Bani Umayyah. The Imam (A.S) remained in this position until when he fainted and was then taken by his followers to his house. Noaman went to Imam's house. Then asked the Imam what was the most difficult time he had to face in Kerbala and during his imprisonment to Kufa and Damascus.
The Imam said, "A-Sham, A-Sham, A-Sham" and then explained that in Sham the family of the Prophet was treated like animals and presented to the court of Yezid like slaves. In this way people of Medina were to see him mourning for his father from then till his death some thirty five years later. It is reported that when the Imam saw water he would weep, remembering the thirst of the martyrs of Kerbala.
When he saw a goat or sheep being slaughtered, he would ask the slaughter if he had fed the animal and given it water. On being assured that this had, indeed, been done, the Imam would weep, saying that his father and other martyrs of Kerbala were slaughtered hungry and thirsty of three days. He held regular mourning session in his house. Those who attended these sessions would then be served with food in the name of his father, Imam Husain (A.S) One day somebody told him.
"O son of Allah's Messenger!. Up to when would you weep like this?" The Imam replied "'O servant of Allah. Prophet Yakub had twelve sons but only one of them (Yusuf) was taken away form him, he wept so much and for such long that his eyes turned white, his head turned gray and his back was bent although his son Yusuf was still alive. Whereas I watched my father, my brother and seventeen members of my family being slaughtered all around me. How could my sorrow come to an end?".
Imam Zainul Abidin (A.S) through such mourning sessions let the world know the reason why it was necessary for Imam Husain (A.S) to sacrifice his life but not accept Yezid as the rightful ruler of the Muslims. The plot of Yezid and his family of Bani Umayyah to destroy Islam was brought out in the open through the Imam's weeping for his father. The second most important thing that the Imam did after returning from Damascus was to spend a lot of his time praying to Allah.
