In ‘aqd, a prose statement is recast as verse; in hall, a poetic statement is rendered as prose.
‘Aqd literally evokes binding: prose material is organized into the formal constraints of verse. Hall evokes loosening: a poem's sense is unfolded through prose syntax.
Neither procedure is mere word shuffling. Both require attention to meaning, structure, and the expressive conditions of the target form.
