«سَمِعْنَا مِنَ الْبَابِ نَبْأَةَ مُسْتَنْبِحٍ ثُمَّ تَلَتْهَا صَكَّةُ مُسْتَفْتِحٍ»
A call came from the door, followed by a knock asking to be admitted.
The narrator supplies sound before sight: a call, then a knock, and only later the visitor’s identity. This sequencing makes the audience share the hosts’ initial uncertainty.
Thumma preserves the order of events and allows a pause. The technique produces suspense through staged perception rather than a direct introductory description of the stranger.
