In poetic examples of qalb, a comparison is sometimes expressed in the inverse direction from the one normally expected. This can strengthen hyperbole by making the thing ordinarily used as a standard appear to derive its quality from the other.
لَوْنُ أَرْضِهِ
The color of his land.
The rhetorical point lies in the unexpected direction of comparison. Simile, hyperbole and qalb can coexist but are not synonyms: inversion concerns relations, simile concerns resemblance, and hyperbole concerns the degree of the attributed quality.
