A classical Arabic bayt normally has two hemistichs: the ṣadr and the ʿajuz. Reading them separately is helpful, but the full meaning often emerges only when both are combined.
In the opening verse, the first hemistich begins with qifā, “stop, you two,” while the second specifies the location where the poet wishes to stop. Without that setting, the command remains incomplete as a poetic image.
A translation should preserve important distinctions such as singular versus dual, imperative versus imperfect, construct phrases, and connecting particles. Fluency should not erase what the Arabic contributes.
