فِيهَا مِصْبَاحٌ الْمِصْبَاحُ فِي زُجَاجَةٍ الزُّجَاجَةُ كَأَنَّهَا كَوْكَبٌ دُرِّيٌّ

“Miṣbāḥ” occurs at the close of one segment and “al-miṣbāḥ” begins the next; “zujājah” is likewise taken up as “al-zujājah.” Each reused noun becomes the topic of a fresh detail.
Rhetorical effect: the description develops successively from lamp to glass to its brilliant likeness. Sound repetition reinforces the unfolding image instead of merely repeating a label.
