The Quran Verse
Surah 24:35:
Allah is the Light of the heavens and the earth. The example of His light is like a niche within which is a lamp, the lamp is within glass, the glass as if it were a pearly [white] star...
This is often praised for its beauty, but scholars note its striking similarity to the Gnostic "Light-Mysticism" and Zoroastrian concepts of the Nur-i-Muhammadi (Light of Muhammad).
The imagery of a "niche" (mishkat) and a "lamp" (misbah) mirrors the architecture of 6th-century Christian monasteries and Syrian churches, where a sanctuary lamp was placed in a niche.
Rather than an original divine metaphor, the "Verse of Light" appears to have absorbed Persian religious symbolism after Islam expanded into Sassanian territory and borrowing Christian language while rejecting the theological framework that makes it coherent in Christianity.
