Attribute: In Māturīdī theology, takwīn is real and eternal.
Product: The mukawwan is its effect and originates at a specific time.
Relation: Its relation is specified with respect to the object and time.
Power: Concerns the possible and the capacity to bring it about.
Will: Concerns specification of the possible at a particular time and in a particular manner.
These five notions are not interchangeable. Showing the compatibility of an eternal attribute and temporal object, explaining the real distinction between power and takwīn, and representing the opposing view accurately are separate analytical tasks.
The next connected issue is will: how an eternal divine will specifies one possibility and one time among the alternatives.
