Al-ghabīṭ names a specific item of travel equipment, combining sheltered seating with transport. Māla is a third-person masculine singular perfect verb; al-ghabīṭu is its subject. The clause therefore means “the litter tilted,” not “the poet bent down.”
Binā contains a preposition and the pronoun “us”; maʿan reinforces their joint presence. Wa-qad māla gives the physical circumstance accompanying the reported words.
