What the thing is
Ibn Rushd al-Jadd was a Mālikī jurist and chief judge in Córdoba who systematised Islamic legal reasoning and issued binding rulings under the Almoravids.
Where it came from
He was a native of Córdoba, active from 1058 to 1126, and rose to prominence in the Almoravid Emirate’s judicial hierarchy.
What it gets right
He systematised uṣūl al-fiqh for the Mālikī school in a fragmented political landscape. His Fatāwā collection set a precedent no earlier Andalusian jurist achieved.
What it gets wrong
He treated Mozarab loyalty as a binary legal condition—treason or dhimmī status—with no room for nuance in lived religious coexistence.
Why it matters now
His approach to legal authority—centralising interpretation, linking fatwās to state policy, and redefining communal boundaries—mirrors modern tensions between religious jurisprudence and civic belonging.
Is it worth your time
Yes—if you care about how legal authority was codified in al-Andalus under Almoravid rule. His work is foundational, not flashy.
