الْقِلَّةُ لَا تَعْنِي الْعَدَمَ.
Scarcity does not mean nonexistence.
This short, complete sentence communicates an important distinction without depending on recovery of a specific missing grammatical element. In that respect it illustrates concision by compression (ījāz al-qaṣr). A response such as al-māʾu ghadan may, by contrast, require the listener to recover an omitted predicate, illustrating ījāz al-ḥadhf.
The distinction is not established by counting words. It turns on whether a complete expression is intrinsically compact or a recoverable element has been deliberately omitted.
