فَتَوَجَّسَتْ رَزَّ الْأَنِيسِ فَرَاعَهَا عَنْ ظَهْرِ غَيْبٍ وَالْأَنِيسُ سَقَامُهَا
She caught the faint sound of people from an unseen direction and was frightened; humans were a source of peril to her.
Tawajjasat means she listened uneasily; razz al-anīs is a faint human sound; rāʿahā means it alarmed her. ʿAn ẓahri ghayb indicates a direction still unseen.
Al-anīs saqāmuhā presents humans as a danger to her. Sound comes before sight and creates suspense.
