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 in a crystal, the crystal is like a shining star, lit from ˹the oil of˺ a blessed olive tree, ˹located˺ neither to the east nor the west, whose oil would almost glow even if untouched by fire. Light upon light! Allah guides whoever He wills to His light. And Allah presents examples for the people. For Allah has ˹perfect˺ knowledge of all things.
Meaning:-
Light: This is a metaphor for the light of guidance in the heart of the believer. (Meaning of Metaphor: is a figure of speech that describes an object or action in a way that isn’t literally true, but helps explain an idea or make a comparison.)
Olive tree: the olive tree is wholesome because it is located in a central place, so it is hit by sunrays all day-long, and, therefore, the oil is of a premium quality.
