وَمَنْ يَكُ أَمْسَى بِالْمَدِينَةِ رَحْلُهُ فَإِنِّي وَقَيَّارٌ بِهَا لَغَرِيبُ
Whoever may have his lodging in Madinah, I and Qiyār are strangers there.
«رَحْلُهُ» denotes lodging or travel gear; Qiyār names the poet's camel. In «فَإِنِّي», inna governs the first-person suffix; the lām in «لَغَرِيبُ» reinforces the predicate.
The intended sense concerns both the speaker and Qiyār, but «قَيَّارٌ» is nominative while the suffix governed by inna is accusative in syntactic position. A smooth translation does not explain this discrepancy. One must identify where the conjunction attaches and whether the predicate of a separate clause has been omitted.
