Allah is the light of the Heavens & 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 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. Allah guides to His light whom He wills. And Allah presents examples for the people,

and  Allah is Knowing of all things.
