«آدِي وِشِّ الضِّيفْ»

A departing speaker presents themself as a guest whose face the others are seeing for the last time. The expression signals an intention to leave those people and never return.

The farewell can carry a sting when the speaker feels unwelcome: the people left behind will no longer have to see this guest. Its force lies in the finality of the departure, not in announcing an arrival.

It can serve as a pointed farewell when someone leaves a group or household with no intention of returning. The guest image is especially apt if the speaker feels disliked by the people they are leaving.
