An-Noor 24:35

Allah is the Light[26] of the heavens and earth. The likeness of His light[27] is that of a niche in which is a lamp; the lamp is in a glass; the glass is like a shining star – it is lit by [the oil of] a blessed olive tree, which is neither of the east nor of the west[28]. Its oil would almost glow, even without being touched by fire. Light upon light; Allah guides to His light whom He wills. Allah sets forth comparisons for people, and Allah is All-Knowing of everything.

[26] i.e., the source and Bestower of light.
[27] The light of guidance in the heart of the believer. [28] As it is located in a central place, so it is hit by sunrays all day long; thus, its oil is of premium quality.

Allāh is the Light[996] of the heavens and the earth. The example of His light[997] is like a niche within which is a lamp;[998] the lamp is within glass, the glass as if it were a pearly [white] star lit from [the oil of] a blessed olive tree, neither of the east nor of the west, whose oil would almost glow even if untouched by fire. Light upon light. Allāh guides to His light whom He wills. And Allāh presents examples for the people, and Allāh is Knowing of all things.

[996] i.e., the source and bestower of light and enlightenment.
[997] His guidance in the heart of a believing servant.
[998] Literally, "a burning wick," which is the essence of a lamp.

35. Allâh is the Light of the heavens and the earth. The parable of His Light is as (if there were) a niche and within it a lamp: the lamp is in a glass, the glass as it were a brilliant star, lit from a blessed tree, an olive, neither of the east (i.e. neither it gets sun-rays only in the morning) nor of the west (i.e. nor it gets sun-rays only in the afternoon, but it is exposed to the sun all day long), whose oil would almost glow forth (of itself), though no fire touched it. Light upon Light! Allâh guides to His Light whom He wills. And Allâh sets forth parables for mankind, and Allâh is All-Knower of everything.

Allah is the Light of the heavens and the earth. The similitude of His light is as a niche wherein is a lamp. The lamp is in a glass. The glass is as it were a shining star. (This lamp is) kindled from a blessed tree, an olive neither of the East nor of the West, whose oil would almost glow forth (of itself) though no fire touched it. Light upon light. Allah guideth unto His light whom He will. And Allah speaketh to mankind in allegories, for Allah is Knower of all things.
