Allah is the Light of the heavens and the earth.

♥ "Allah is the Light of the heavens and 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. [Such niches are] in mosques which Allah has ordered to be raised and that His name be mentioned therein; exalting Him within them in the morning and the evenings...[Are] men whom neither commerce nor sale distracts from the remembrance of Allah and performance of prayer and giving of zakah. They fear a Day in which the hearts and eyes will [fearfully] turn about - That Allah may reward them [according to] the best of what they did and increase them from His bounty. And Allah gives provision to whom He wills without account." ♥ (Surah Noor, 35-38)
