فَدَخَلْتُهَا خَاوِيَ الْوِفَاضِ بَادِيَ الْإِنْفَاضِ
I entered it with my provisions empty and my poverty apparent.
دخلتها tells us what action occurred. خاوي الوفاض and بادي الإنفاض describe the narrator's condition when he entered, functioning as expressions of ḥāl (circumstantial state).
“What place did he enter?” — Ṣanʿāʾ. “In what condition?” — With an empty bag and visible destitution.
