titular head of the Māturīdīyah school of theology, which came to be one of the most important foundations of Islāmic doctrine.

Except for the place and time of Māturīdī's death, almost nothing is known about the details of Māturīdī's life. He lived during a time when the Muʿtazilites, a Muslim sect, were using the techniques of Greek logical argument to attack what had come to be accepted as orthodox Muslim theology. Māturīdī seized the offensive by using these same arguments as a means of defending orthodox theology. In fact, such use of logic was widespread, and it is not clear why Māturīdī came to be accepted as a protagonist of such thought or why reference to him came to supersede reference to Abū Ḥanīfah (d. 767), the Muslim theologian who seems to have been the first to adopt the methods of the Muʿtazilites. Māturīdī is also noted for his emphasis on the morality of human responsibility, which contributed to the “humanization” of orthodoxy that occurred in the following centuries.
