«مِنْ دَخَلْ بِيتَكْ جَابِ الْحَق عَلِيكْ»

In the saying's social logic, a host is bound to yield to anyone who has crossed his threshold. The caller's wishes now press on the household, and turning them down would seem ungracious, because the obligation runs from the person visited toward the person who came, never the reverse.

Beneath this lies the idea that arriving in person is itself a peace offering. A caller who may have done you wrong wipes away much of that fault simply by making the trip, and the effort he spent coming is read as goodwill that deserves to be answered in kind.

Said when a caller, especially one arriving after a falling-out or bringing a request, is expected to be indulged. The tone is conciliatory: the trouble of coming obliges the host to respond generously. Using it to claim a host gains power over a guest reverses its sense.
