Relation (taʿalluq) denotes how an attribute is considered with respect to its object. It should not automatically be imagined as a bodily motion or a new state arising in the divine essence.
When a creature begins at a given time, that is a change in the creature's condition. It does not follow that an analogous temporal change occurs within God. Treating the divine attribute like a changing created object is a category error within this framework.
The same caution applies to knowledge: an object being nonexistent and later existent does not, merely by that transition, prove the origination of divine knowledge.
