Waffaqaka Allāh and raḥimahu Allāh use past morphology to present a hoped-for blessing as though achieved. Taʾtīnī ghadan uses a present/imperfect form to speak of the addressee’s future action as if it were settled, thereby urging compliance.
Both are examples of declarative forms used with inshāʾ force, but the first emphasizes hope or prayer while the second influences an addressee’s future behavior.
