The fifth lecture in the Shi鈥榠 Studies Lecture Series was entitled The Zaydi Reception of Abu l-Husayn al-Basri and Ibn al-Malahimi: Husam al-Din 鈥楢bd Allah b. Zayd al-鈥楢nsi (d. 1268 CE) and his Kitab al-Mahajja al-bayda. It was delivered by Professor Sabine Schmidtke, Professor of Islamic Studies at Freie Universit盲t Berlin, in May 2010.
Referring to the 12th century CE, Professor Schmidtke argued that, as a result of the unification of the Caspian Zaydiyya and the Zaydis聽in Yemen during the imamate聽of Abu Talib al-akhir (d. 1126 CE), a massive transfer of knowledge from Iran to Yemen began. This gradually increased throughout the 12th century CE, until the death of their Imam al-Mansur bi-llah 鈥楢bd Allah b. Hamza in 1217 CE. This transmission led to a cultural revival: as a result of which the cultural center of Zaydism gradually shifted from the coastal regions south of the Caspian Sea to Yemen. In tandem with this was a renewed blossoming of Mu鈥榯azilite theology.
Among the Mu鈥榯azilite writings that reached Yemen during the 12th and 13th centuries, CE were works of qadi聽l-qudat 鈥楢bd al-Jabbar al-Hamadani, along with works written by his students and companions. 鈥楢bd al-Jabbar was the head and leading scholar of the Bahshamiyya, a major branch of the Mu鈥榯azila in his time. During this period, the Yemeni Zaydis were also introduced to the teachings of Abu l-Husayn al-Basri (d. 1045 CE), the former student of 鈥楢bd al-Jabbar who later became known as the founder of the last innovative school within Mu鈥榯azilism.
The majority of Yemeni Zaydis of the 12th century CE were faithful followers of the Basran and, more specifically, Bahshamite doctrines. Gradually, however, the teachings of Abu l-Husayn al-Basri gained influence. Professor Schmidtke concluded with the discussion of this process and highlighted one of the earliest Yemeni Zaydis to explicitly prefer some of the doctrinal positions of Abu l-Husayn al-Basri and Ibn al-Malahimi to those of the Bahshamiyya, 鈥楢bd Allah b. Zayd al-鈥楢nsi (d. 1268 CE).
