«زَيْدٌ كَالْأَسَدِ فِي الشَّجَاعَةِ»
Zayd is like a lion in courage.
This example states all four elements of comparison: Zayd, the lion, the particle kāf, and courage. By contrast, the dawn “breathing” does not express both comparison terms or an overt particle; its imagery is inferred from the attributed action.
A shared idea of similarity does not make the two grammatical and rhetorical structures identical.
