أَوْقَدَتْهَا بَيْنَ الْعَقِيقِ فَشَخْصَيْنِ ۞ بِعُودٍ كَمَا يَلُوحُ الضِّيَاءُ
Translation: She lit the fire between al-ʿAqīq and Shakhṣayn with wood, and its brightness appeared visibly.
Al-ʿAqīq and Shakhṣayn are place names. Bi-ʿūdin refers to the wood used to kindle the fire, and al-ḍiyāʾ denotes brightness.
The previous verse emphasized remoteness; this one gives the scene material detail—location, fuel and light. The flame becomes vividly observable without eliminating the difficulty of reaching its source.
