الإيجاز والإطناب والمساواة
Brevity, beneficial expansion and proportional expression.
Ijaz presents the intended meaning compactly without losing what is needed. Itnab extends expression for a communicative benefit. Musawah uses expression proportionate to the intended content, without a marked reduction or a beneficial addition.
Shortness alone does not ensure excellence, nor does length alone imply needless verbosity. The assessment depends on contextual purpose and rhetorical benefit.
