The classical expression “kathīr al-ramād” (“one with abundant ashes”) can be used to praise generosity. Its outward content refers to ashes, while the intended quality is open-handedness. The older use of wood fires and hospitality customs supplies the necessary background.
Step 1: Many ashes → fires were lit frequently.
Step 2: Frequent fires → substantial cooking.
Step 3: Substantial cooking → hospitality to many guests in the relevant context.
Step 4: Willingly serving and feeding guests → the intended praise of generosity.
These are customary interpretive links, not exceptionless physical laws for every home or historical period. The example illustrates how intermediate steps affect the clarity of a rhetorical inference.
