«إِذْ وَقَفَ بِنَا شَخْصٌ»
Suddenly, a person stood before us.
The short expression “Suddenly someone stood before us” interrupts an ongoing gathering. The narrator does not first provide the visitor’s full biography; he shows the act of appearing. The audience must respond before it has enough information to classify the stranger.
The temporal particle marks an interruption in the scene’s rhythm. A literary discussion can become a test of sympathy or persuasion as soon as an outsider addresses it. This is the structural difference between a continuing description and an event that changes the direction of the story.
