In praise and dispraise, the object may be left implicit in one part of the sentence while its expression elsewhere establishes the precise force of the claim. With «مثلا», the hearer learns not merely that someone searched but that no comparable person was found.
An important caution follows: ellipsis must not be credited with every rhetorical virtue. Deletion can make a statement economical, expression can remove uncertainty, and their deliberate combination can produce the main effect.
Before labeling a construction, one must identify which information is genuinely new to the hearer.
