Philosophers as represented here: an effect follows necessarily from essence, rather than being specified by choice.
Najjāriyyah: God is willing by His essence without a distinct real attribute of will.
Some Muʿtazilīs: will is originated but subsists in no locus.
The disagreements are not identical. The first concerns necessary production, the second the reality of the attribute, and the third origination and locus.
In contrast, the Māturīdī account affirms real, eternal will subsisting in God, related to the specification of the forms and times of created things.
