Imam Muḥammad al-Bāqir was one of the most erudite Muslims of his age, and played a significant role in the history of early Islam. At once a versatile leader and scholar in the eighth-century Muslim world, he was also an authority on the exegesis of the Qur’an, the traditions of the Prophet, and all matters relating to the rites, rituals and practice of Islam.

Using hitherto largely ignored Shīʿī sources, both published and unpublished, Arzina R. Lalani explores al-Bāqir’s pivotal contributions to Islamic thought in its early formative period, contributions that were powerfully to affect developments in Shīʿī law, theology and religious practice. This study gives particular attention to al-Bāqir’s vital role in the formulation of the Shīʿī doctrine of imamate.

Dr Lalani’s work presents the first systematic account of the life, career and teachings of this brilliant eighth-century luminary. It will be of great interest to students of islamic law, history and theology and will also be of interest to modern Shīʿī communities.
