God Has No Eternal Attributes Distinct From His Essence

The Mutazila, a rationalist theological school that flourished in eighth and ninth century Basra and Baghdad, argued that affirming God's attributes, knowledge, power, will and the rest, as eternal realities existing alongside God's essence would compromise the strict unity, tawhid, that Mutazilite theologians treated as Islam's most fundamental commitment, since positing several eternal things alongside God's own eternal essence risked multiplying the eternal into something resembling several co-eternal beings rather than the single, indivisible God the doctrine of tawhid requires. Montgomery Watt's survey of Islamic creedal statements presents the Mutazilite resolution as holding that God's attributes are not separate eternal entities distinct from His essence, nor are they simply identical with it in an ordinary sense, but exist in a relationship the school's theologians worked to define carefully enough to preserve both divine unity and the meaningfulness of describing God as knowing or powerful at all. Marshall Hodgson's history of the classical Islamic world situates this position as the most theologically consequential of several Mutazilite doctrines, opposed vigorously by the later Ash'ari school, which affirmed God's attributes as real and eternal, a dispute that shaped the direction of Sunni theology for centuries after the Mutazila's own political fortunes declined.

Mutazilite theology moved from academic debate to state policy under the Abbasid caliph al Mamun, who in 833 launched an inquisition known as the mihna requiring scholars and officials to publicly affirm doctrines associated with Mutazilite rationalism, most prominently that the Quran was created rather than eternal, a position closely bound up with the school's wider rejection of eternal realities existing alongside God's essence, since an eternal, uncreated Quran would itself constitute exactly the kind of second eternal thing the doctrine of divine unity without eternal attributes was meant to rule out. Ahmad ibn Hanbal's public refusal to affirm the doctrine, and his imprisonment for that refusal under al Mamun's two successors, made him a symbol of traditionalist resistance to state enforced rationalist theology, and Marshall Hodgson's history describes the mihna's ultimate failure, formally ended by caliph al Mutawakkil in 848, as a turning point after which Mutazilite theology lost official patronage across most of the Sunni world even as it continued to shape later Twelver Shia and Zaydi theological method, both of which retained versions of the Mutazilite position on divine attributes and unity long after Sunni orthodoxy had settled decisively with the rival Ash'ari school.
