وَجَاشَتْ إِلَيْهِ النَّفْسُ خَوْفًا وَخَالَهُ
مُصَابًا وَلَوْ أَمْسَى عَلَى غَيْرِ مَرْصَدِ
Meaning: His spirit surges with fear, and he imagines himself struck by disaster even when he has reached a place outside an expected place of ambush.
Jāshat ilayhi al-nafs depicts the inward agitation of fear. Khālahu muṣāban expresses a fearful judgment about his own condition. ʿAlā ghayri marṣad keeps the distinction between the feeling and the external circumstance: the traveler may imagine imminent destruction even without an actual attack.
