The terms striker (ḍārib), striking (ḍarb), and the one struck (maḍrūb) have different meanings. Likewise the Creator, takwīn and the created product need not be treated as conceptually identical. The first identifies an agent, the second an act, the third a recipient or effect.
This analogy helps distinguish agent, act and object. It does not imply that divine creating requires bodily motion such as human striking.
An opponent may argue that human striking does not exist without what is struck, hence eternal takwīn cannot lack its product. The response is that properties of an originated human act cannot simply be transferred to an eternal divine attribute.
