The mihna

833–848 · Baghdad (Baghdad, Iraq)

The caliphs al-Ma'mun and his two successors impose the mihna, an inquisition requiring officials and scholars to affirm the createdness of the Qur'an, the Mu'tazila doctrine; Ahmad ibn Hanbal's refusal and flogging make him Sunni Islam's emblem of resistance, and al-Mutawakkil abandons the test.

How the Tradition Tells It

The mihna fixed a boundary the schools still trace: Ash'ari theology affirms the Qur'an as God's uncreated speech with rational argument, Hanbali traditionalism refuses the speculative framing itself, and the Mu'tazila, who lost the inquisition's patronage, survive as a school chiefly in the commentary tradition and in Zaydi theology.
