«وَقَدْ عَرَا فِنَاءَكُمْ مُعْتَرًّا»
He has come into the space before your home as one in need.
Fināʾ is the open space or forecourt by a dwelling. ʿArā indicates arriving, and muʿtarr describes a needy visitor seeking kindness, even without an explicit demand.
The poem now moves from the journey itself to the visitor's immediate location at the hosts' door.
