Kamal al-Din Maytham ibn Ali (Arabic: كمال الدين ميثم ابن علي|translit=Kamāl al-Dīn Maytham ibn ʿAlī; 1238–1299), commonly known by the al-Bahrani (Arabic: البحراني|translit=al-Baḥrānī), was a leading thirteenth-century Twelver Shia theologian, author and philosopher. Al Bahrani wrote on Twelver doctrine, affirmed free will, the infallibility of prophets and imams, the appointed imamate of `Ali, and the occultation of the Twelfth Imam.[1] Along with Kamal al-Din Ibn Sa’adah al Bahrani, Jamal al-Din ‘Ali ibn Sulayman al-Bahrani, Maytham Al Bahrani was part of a thirteenth-century Bahrain school of theology that emphasised rationalism.[2]
At the same time, Maytham Al Bahrani was profoundly influenced by the disciplines of philosophy and mysticism.[3] He wrote widely on such theology related philosophical issues as epistemology and ontology.
Al Bahrani's scholarship took in both Imami and Sunni sources; according to University of Bahrain academic, Ali Al Oraibi:
In the thirteenth century, Twelvers – particularly mystics[4] – were a growing influence in Bahrain, which had previously been dominated by the Ismaili Qarmatian sect.
The Bahrain school of thought's integration of philosophy and mysticism into Imami Shi'ism had an enduring legacy, influencing fourteenth-century theologians such as Ibn Abi Jumhur al-Ahsai'i. Politically, the intellectual vitality of al-Bahrani and his contemporaries is credited with converting the Ilkhanid monarch, Mohammed Khudabandeh, to convert to Shi'ism and announce a Shia state.[5]
He is buried in Mahooz, Bahrain, where a shrine and mosque have been constructed.
