What distinction does the Māturīdī answer draw against identifying takwīn with power?

The Attribute of Takwīn: Reality, Eternity, Created Effects and Relations

• Capacity versus the actual principle of origination
• Will is the actual principle of creating while power only specifies time
• Takwīn is knowledge of the act, whereas power is its specification
• Capacity and actual origination are identical with no conceptual distinction
