فَلَمَّا بَلَغَ الْبَابَ، قَالَ: قَدْ عَادَ الْغَائِبُ سَالِمًا.
When he reached the door, he said: the absent person has returned safely.
Falammā balagha l-bāb sets the moment of disclosure. The announcement follows, and qad with the perfect verb highlights realised occurrence, a natural reassurance in a scene of anxious waiting.
If the news were disclosed before the arrival at the door, much of the suspense would vanish. Temporal arrangement thus contributes directly to the rhetoric of the story.
