On Olive Oil

God is the light of the heavens and the earth
The likeness of his light is a niche
wherein is a lamp
(the lamp in a glass, the glass as it were a glittering star)
kindled from a blessed tree,
an olive that is neither of the east nor of the west
whose oil well-nigh would shine, even if no fire touched it;
Light upon Light!

(Koran, xxiv: 35)

Please note that God's light was not compared to corn or safflower, or heaven forbid, canola!
