“God is the light of the heavens and the earth.
The semblance of His light
Is that of a niche in which is a lamp,
The flame within a glass,
The glass a glittering star as it were,
Lit with the oil of a blessed tree,
The olive, neither of the East nor of the West,
Whose oil appears to light up
Even though fire touches it not,
Light upon light.
God guides to His light whom He will.
So does God advance precepts of wisdom for men,
For God has knowledge of every thing.”

Al-Qur’an 24:35 (Ahmed Ali)
