Imam Musa Kazim is the Seventh Apostolic Imam. His epithet was Abu Hasan and his famous title was Kazim. His matchless devotion and worship of God has also earned him the title of "Abdussalih" (virtuous slave of God). Generosity was synonymous with his name and no beggar ever returned from his door empty handed.
Even after his death, he continued to be obliging and was generous to his devotees who came to his holy tomb with prayers and behests which were invariably granted by God. Thus, one of his additional titles is also "Babul-Hawaij" (the door to fulfilling needs).
The Holy Imam Musa Kadhim was the son of Imam Jafar Sadiq, the Sixth Imam. The name of his mother was Hamidah, the daughter of a noble man hailing from the states of Barbary.
Imam Musa Kazim passed twenty years of his sacred life under the gracious patronage of his holy father. His inherent genius and gifted virtues combined with the enlightened guidance and education from the Holy Imam Jafar Sadiq, showed in the manifestation of his future personality.
He was fully versed with the Divine Knowledge even in his childhood.
"Allamah Majlisi relates that once Abu Hanifah happened to call upon the holy abode of Imam Jafar Sadiq to ask him about some religious matters. The Imam was asleep and so he kept waiting outside till the Imam‘s awakening. Meanwhile, Imam Musa Kadhim, who was then five years old, came out of his house. Abu Hanifah, after offering him his best compliments, enquired: "O the son of the Holy Prophet! What is your opinion about the deeds of a man? Does he do them by himself or does God make him do them?" "O Abu Hanifah", the five years old Imam replied at once, in the typical tone of his ancestors, "the doings of a man are confined to three possibilities. First, that God alone does them while the man is quite helpless. Second, that both God and the man do equally share the commitment. Third, that man does them alone. Now, if the first assumption is true, it obviously proves the unjustness of God who punishes His creatures for sins which they have not committed. And if the second condition be acceptable, even then God becomes unjust if He punishes the man for the crimes in which He is equally a partner. But the undesirability of both these conditions is evident in the case of God. Thus, we are naturally left with the third alternative to the problem that men are absolutely responsible for their own doings."
The Holy Imam Jafar Sadiq breathed his last on 25th ShawwaL 148 AH, and with effect from the same date Imam Musa al-Kazim succeeded the holy office of Imamate as the Seventh Imam. The period of his Imamate continued for thirty-five years.
In the first decade of his Imamate, Imam Musa Kazim could afford a peaceful execution of the responsibilities of his sacred office and carried on the propagation of the teachings of the Holy Prophet. But soon after, he fell a victim to the ruling kings and a greater part of his life passed in prison.
Imam Musa Kazim lived under the most crucial times in the regimes of the despotic "Abbasid kings who were marked for their tyrannical and cruel administration. He witnessed the reigns of Mansur Dawaniqi, Mahdi and Harun. Mansur and Harun were the despotic kings who put a multitude of innocent descendants of the Holy Prophet to the sword.
Thousands of these martyrs were buried alive inside walls or put into horrible dark prisons during their lifetime. These depraved caliphs knew no pity or justice and they killed and tortured for the pleasure they derived from human sufferings.
The Holy Imam was saved from the tyranny of Mansur because the king, being occupied with his project of constructing the new city of Baghdad, could not get time to turn towards victimizing the Imam. By 157 AH the city of Baghdad was built. This was soon followed by the death of its founder a year later. After Mansur, his son Mahdi ascended the throne. For a few years he remained indifferent towards the Imam. When in 164 AH he came to Medina and heard about the great reputation of the Imam, he could not resist his jealousy and the spark of his ancestral malice against the Ahlul-Bayt was rekindled. He somehow managed to take the Imam along with him to Baghdad and got him imprisoned there. But after a year he realized his mistake and released the Imam from jail. Mahdi was succeeded by Hadi who lived only for a year. Now, in 170 AH, the most cruel and tyrannical king Harun appeared at the head of the "Abbasid Empire. It was during his reign that the Holy Imam passed the greater part of his life in a miserable prison till he was poisoned.
Time and circumstances did not permit the Holy Imam Musa al-Kazim to establish institutions to impart religious knowledge to his followers as his father, Imam Jafar as-Sadiq and his grandfather, Imam Muhammad Baqir had done. He was never allowed to address a congregation. He carried on his mission of preaching and guiding people quietly.
In 179 AH, Harun visited Medina. The fire of malice and jealousy against the Ahlul-Bayt was kindled in his heart when he saw the great influence and popularity which the Holy Imam enjoyed amongst the people there. He got the Imam arrested while he was busy in prayer at the tomb of the Holy Prophet and kept him in prison in Baghdad for a period of about four years.
On the 25th Rajab 183 AH, he got the Imam martyred by poison. Even his corpse was not spared humiliation and was taken out of the prison and left on the Bridge of Baghdad. His devotees, however, managed to lay the holy body of the Imam to rest in al-Kazimian (Iraq).
