Two questions must be separated in qalb: whether the expression departs from the expected relation, and whether that departure contains a subtle rhetorical consideration. Reversal alone does not prove eloquence.
The text reports objections that inversion contradicts the intended relation, alongside explanations in which context makes the meaning clear and the inverted image carries a special exaggeration or effect.
A careful reading identifies the ordinary relation, the reversed form, the contextual indication and the resulting literary effect instead of automatically approving every inversion.
