Allah is the light of the heavens and the earth the parable of his light is as if there were Niche and within it a Lamp : the lamp enclosed in Glass the glass as it were a brilliant star lit from a beloved Tree . An Olive, neither of the East no of the West, whose oil is well-nigh Luminous. Though fire scarce touched it; Light upon Light.
(24:35)
The verse is called Alnur, is the verse that people use to proof Imamt of Ali as he was the tree from neither east nor west.
