فَلَمَّا عَرَفْتُ الدَّارَ قُلْتُ لِرَبْعِهَا ۞ أَلَا انْعَمْ صَبَاحًا أَيُّهَا الرَّبْعُ وَاسْلَمِ
Meaning: Once I knew the dwelling, I said to its deserted site: “May your morning be pleasant, old abode, and may you remain safe.”
Fa-lammā ʿaraftu al-dāra completes the act of recognition, and qultu li-rabʿihā turns the empty dwelling into the addressee. Alā inʿam ṣabāḥan is a conventional early Arabic greeting and wish for well-being; a wooden literal paraphrase would lose its social and emotional force.
