وَقَفْتُ بِهَا مِنْ بَعْدِ عِشْرِينَ حِجَّةً ۞ فَلَأْيًا عَرَفْتُ الدَّارَ بَعْدَ تَوَهُّمِ
Meaning: I stopped there after twenty years and, only with difficulty and after an uncertain impression, managed to recognize the dwelling.
ʿIshrīna ḥijjatan uses ḥijjah to mean a year, not the ritual pilgrimage in this context. Fa-laʾyan suggests laborious, delayed recognition, and baʿda tawahhum the uncertain impression that preceded it. The tentative question in verse 1 now begins to find an answer.
