Māturīdism or Māturīdī theology (الماتريدية: al-Māturīdiyyah) is one of the main Sunnī schools of Islamic theology, developed and codified by the Persian Muslim scholar, Ḥanafī jurist, reformer (mujaddid), and scholastic theologian Abū Manṣūr al-Māturīdī in the 9th–10th century.

Ethics have an objective existence and humans are capable of recognizing it through reason alone. Although humans are intellectually capable of realizing God, they need revelations and guidance of prophets and messengers, because human desire can divert the intellect and because certain knowledge of God has been specially given to these prophets (e.g.
