The scholars call this verse as the “Verse of Radiance”, because it describes in great detail the radiance of faith and the darkness of disbelief.
Allah is the Light of the heavens and the earth. The example of His light is that of a niche in which there is a lamp; the lamp is in a glass - the glass looks like a brilliant star - it is lit by (the oil of) a blessed tree, the olive, which is neither eastern, nor western. Its oil is about to emit light even if fire has not touched it - (it is) light upon light. Allah guides to His light whomsoever He wills. And Allah describes examples for the people, and Allah knows everything well. [24:35]
