CaseDiagnostic
Purposeful qalbNormal relation recoverable, inversion meaningful, contextual clue present
Unmotivated reversalNo reliable clue and no intelligible rhetorical purpose
Ordinary rearrangementPermitted word order variation without reversing the intended relation
Moving a phrase forward or backward is not itself qalb if the semantic relation stays unchanged. Nor does an unintelligible reversal gain literary value merely through unusual arrangement.
