allah is the light of the heavens and the earth the example of his light is like a niche in which is a lamp the lamp is in a glass the glass is as if it were a star shining like a pearl kindled by the blessed olive tree neither of the east nor of the west – it is close that the oil itself get ablaze although the fire does not touch it light upon light allah guides towards his light whomever he wills and allah illustrates examples for mankind and allah knows everything. 
الله نور السماوات والأرض مثل نوره كمشكاة فيها مصباح المصباح في زجاجة الزجاجة كأنها كوكب دري يوقد من شجرة مباركة زيتونة لا شرقية ولا غربية يكاد زيتها يضيء ولو لم تمسسه نار نور على نور يهدي الله لنوره من يشاء ويضرب الله الأمثال للناس والله بكل شيء عليم
