Designation as the Imam , located in
Karbala Muhammad al-Jawad was about seven years old when his father al-Rida died in 203 AH (818). Even as the only child of al-Rida, the succession of the young Muhammad to the imamate became controversial, but did not result in permanent divisions of the Shia community. At the time, al-Mas'udi notes the confusion () among the Imamite Shias about the qualifications of the young al-Jawad for the imamate. As related by al-Mas'udi and Majlesi, several supporters of al-Rida thus gathered in Baghdad at the house of Abd al-Rahman ibn al-Hajjaj, a distinguished companion of the three previous Imams, namely,
Ja'far al-Sadiq (), al-Kazim, and al-Rida. Of those present, Yunus ibn Abd al-Rahman reportedly suggested they choose a temporary leader until al-Jawad reached adulthood. But the view that prevailed was that adulthood is not a prerequisite for wisdom. There is also the account in
Ithbat al-wasiyya and elsewhere, saying that the prominent Shias from across the empire tested the young al-Jawad during the Hajj season and their doubts about him were dispelled. There are also reports about the direct or indirect designation () of al-Jawad as the next imam by his predecessor. These are often narrated by the inner circle of al-Rida, thus signifying their visible role in consolidating the imamate of the young al-Jawad. An example of indirect designation is the statement referring to the young al-Jawad as "the greatest blessing for the Shia," ascribed to al-Rida in the canonical
Kitab al-Irshad and other sources. Elsewhere when al-Husayn ibn al-Qiayama questioned the imamate of al-Rida for his lack of an heir at the time, he responded that he would have a son to succeed him. According to Wardrop, as the only son of al-Rida, recognition of al-Jawad as the heir to the imamate was to be expected, adding that there is considerable evidence in the hadith literature against the horizontal transference of the imamate between brothers after
Hasan ibn Ali () and
Husayn ibn Ali (), the second and third of the Twelve Imams. Wardrop points out that there were very few qualified alternatives to al-Jawad anyway, naming his uncles, Ahmad ibn Musa and Abdallah ibn Musa, and also a different
Hasanid with the latter name. That there was no clear alternative to al-Jawad is also the view of the Muslim jurist
Hossein Modarressi. The attention al-Jawad received from al-Ma'mun, who married him to his daughter, may have also strengthened the case for al-Jawad. Wardrop thus concludes that the main challenge to the imamate of al-Jawad was his young age, given that the imamate was viewed by the Shia as the ultimate source of knowledge () and guidance. A group of followers of al-Rida thus accepted the imamate of his brother, Ahmad ibn Musa, who had earlier rivaled al-Rida. Another group joined the
Waqifites, who considered al-Kazim to be the last Imam and expected his return as
Mahdi, the promised savior in Islam. Some of these apparently argued that their imam could not be a child. According to Madelung, some others, who had opportunistically backed the imamate of al-Rida after his appointment as the heir apparent, had now returned to their Sunni or
Zaydi communities.
Precedents As for precedents, there were no child imams before al-Jawad, even though Ali ibn Abi Talib professed Islam at the age of about ten, and Hasan and Husayn formally pledged their allegiance to the prophet when they were about six. Imamite authors have noted that
Jesus received his prophetic mission in the Quran when he was still a child, suggesting that al-Jawad also received the requisite perfect knowledge of all religious matters through divine inspiration from the time of his succession, irrespective of his age. Similar statements are also attributed to al-Rida, "This [his age] does not harm him [al-Jawad], Isa [Jesus] became God's () when he was three years old." The related Quranic verse 19:12 includes, "We gave him
John the Baptist () as a child." Even so, some among the Shia still debated as to whether the young Imam was equal to an adult Imam in every aspect, Indeed, there already were traditions attributed to earlier Imams asserting that each Imam would inherit the full knowledge of his predecessor upon his death.
Network of representatives To organize the affairs of a growing Shia population, which had expanded far to the east of Iraq and Arabia, the young al-Jawad relied heavily on his representatives or agents (, ) throughout the empire. This underground network of agents across the Abbasid empire was founded by his grandfather al-Kazim () and maintained by his son al-Rida. There is even some evidence that an early network existed under al-Sadiq (). This network guided the financial and religious affairs of the Imamite Shias. After the death of al-Rida, it took possibly up to four years for the imamate of al-Jawad to consolidate. In this period of uncertainty, the network of likely continued to function, but did so more independently than ever before. Wardrop suggests that this level of autonomy continued throughout the childhood of al-Jawad. After al-Rida, some agents remained loyal to his successor, possibly after testing him during the Hajj season. These included Abd al-Aziz ibn al-Muhtadi,
Ayyub ibn Nuh, and Yahya ibn Abi Imran. Some others did not, including perhaps Safwan ibn Yahya, Muhammad ibn Sinan, Zakariyya ibn Adam, and Sa'd ibn Sa'd. There are conflicting reports about these four and whether they withheld their collected alms from al-Jawad, but some of them are said to have later returned to the Imam. Because of the relative isolation of al-Jawad by the Abbasids, the Imamite Shias normally communicated with their Imam through his agents, except during Hajj when they met directly with him. During al-Jawad's imamate, Shia activists were dispatched to Egypt and elsewhere, as reported by the Twelver traditionist
Ahmad ibn Ali al-Najashi (). They were apparently successful and an account by the Twelver traditionist
Muhammad ibn Ya'qub al-Kulayni () describes how
Ali ibn Asbat visited al-Jawad on behalf of the Egyptian Imamites. Among the agents of al-Jawad were
Ali ibn Mahziar Ahvazi in
Ahvaz, Ibrahim ibn Muhammad Hamdani in
Hamedan, Yahya ibn Abi Imran in
Rayy, Yunus ibn Abdulrahman and Abu Amr al-Hadhdha' in
Basra, Ali ibn Hasan W'aseti in
Baghdad, Ali ibn Asbat in Egypt,
Safwan ibn Yahya in
Kufa, Saleh Ibn Muhammad Ibn Sahl and
Zakaria ibn Adam Ash'ari Qomi in Qom. In addition to these agents, al-Jawad sometimes sent special representatives to cities to collect religious taxes, including
Khums. Some followers of al-Jawad received permission to work within the Abbasid government for the benefit of the Shia community. These included Muhammad ibn Isma'il ibn Baz'i and Ahmad ibn al-Hamza al-Qomi in the vizierate, Husayn ibn Abd-Allah al-Neishaburi, the ruler of
Bost and
Sistan, Hakam ibn Alia' al-Asadi, the ruler of
Bahrain, and Nuh ibn Darraj, the of Baghdad and then Kufa. Some of these figures are now known to have secretly paid their Khums to al-Jawad. Towards the end of al-Jawad's life, the organization and activities of his agents further expanded. Some of his followers became integrated within the Abbasid army, while he announced his successor, Ali al-Hadi, through his main agent, Muhammad ibn al-Faraj, or through another companion, Abu al-Khayrani.
Role in Shia revolts Muhammad al-Jawad adopted a quiescent attitude and
kept aloof from politics, similar to many of his predecessors. Nevertheless, Hussain links the 210 AH (825) uprising in
Qom to the political activities of al-Jawad's agents, even though the Imamite sources are silent about any military involvement of his underground organization. Prior to this revolt, residents of Qom, a rising Shia center, had called on al-Ma'mun to lower their taxes as he had done for the city of
Rayy. The caliph rejected their appeal, then suppressed their subsequent revolt, and substantially raised their taxes. This is detailed by the Twelver traditionist
Ibn Shahrashub (), who writes that the Abbasid army demolished the wall surrounding the city, killed many, and nearly quadrupled the taxes. Among those killed was a prominent participant in the uprising, named Yahya ibn Imran, who might have been a representative () of Muhammad al-Jawad. The attitude of al-Jawad towards this uprising, however, remains unclear, as the Imamite sources are silent about this uprising and its connection to al-Jawad or lack thereof. Probably connecting al-Jawad to Shia rebellions, al-Ma'mun summoned the former from Medina to Baghdad in 215 AH (830) and married his daughter Umm Fazl to him. This marriage, however, did not win al-Ma'mun the Shia support, nor did it stop the uprisings in Qom. Indeed, some reports by al-Tabari and Ibn al-Athir add that among the rebel leaders who had been exiled to Egypt, Ja'far ibn Dawud al-Qomi later escaped and rose again in Qom, defeating the Abbasid army in 216 AH. The Shia uprisings continued even after his execution in 217 AH by the Abbasids. After succeeding al-Ma'mun, al-Mu'tasim summoned al-Jawad to Baghdad in 220 AH (835) and held him under close surveillance, probably to ascertain his role in the Shia uprisings.
Companions and narrators of hadith Shaykh Tusi () has listed one hundred and sixteen narrators of hadith from al-Jawad, though only a few of them were his trusted companions, including Ali ibn Mahziar Ahvazi, Abu Hashim Dawud ibn al-Qasim al-Ja'fari,
Abd al-Azim al-Hasani,
Ahmad ibn Muhammad al-Bazanti, Ali ibn Asbat Kufi,
Uthman ibn Sa'id al-Asadi, and Amro ibn Firat. In particular, Ibn Mahziar was the agent of al-Jawad in Ahvaz and wrote two books, namely,
Kitab al-Malahim and ''Kitab al-Qa'im'', about occultation, which is the
eschatological belief that
Mahdi, a descendant of the Islamic prophet Muhammad, has already been born and subsequently concealed from the public. The two sons of Ibn Mahziar, named Ibrahim and Muhammad, later served as the representatives of the twelfth Imam in Ahvaz. The Imam distanced himself from the
Ghulat () who believed in the divinity of Imams. Among them were
Abu l-Khattab, Abu al-Samhari, and Ibn Abi Zarqa, who are said to have defamed Shia by forging traditions and attributing them to the Imams and introducing themselves as their representatives.
In Shia sources, al-Jawad is credited with some ( ), that is, supernatural acts or miracles sometimes attributed to saints in Islam. These include speaking at the time of his birth, (teleportation in Islamic mysticism) from Medina to Khorasan for the burial of his father al-Rida, miraculously healing the sick, fulfillment of his prayers for friends and against his enemies, informing about the inner secrets of people, predicting future events, and particularly his death. These are often cited by the Shia as proof of his imamate. A subtle story of this kind in
Bihar al-Anwar and
Kitab al-Kafi is told on the authority of Abd-Allah ibn Razin. When visiting the Imam, he decided to gather some of the earth upon which al-Jawad had set foot, a desire that he later deemed sinful. However, his attempts to tactfully do so were all thwarted by al-Jawad, who subtly changed his daily routines. This continued to the point that it surprised the attendant of Imam and let Abd-Allah realize that al-Jawad was aware of his sinful determination. It was only after Abd-Allah resolved to give up that al-Jawad returned to his usual routine.
Successor After the death of al-Jawad in 220 AH (835), the majority of his followers acknowledged the imamate of his son Ali, later to be known by the epithets al-Hadi () and al-Naqi (). Similar to his father, Ali was also a minor when he succeeded him in 220 AH (835) at the age of about seven. The will attributed to al-Jawad in
Kitab al-Kafi stipulates that Ali would inherit from him and be responsible for his younger brother, Musa, and his sisters. Muhammad al-Jawad is also said to have announced the succession of Ali through his main agent, Muhammad ibn al-Faraj, or through Abu al-Khayrani. This messenger relayed the designation to the assembly of companions after the death of al-Jawad and the majority there is reported to have agreed on the imamate of Ali al-Hadi. == Legacy ==
