Bismillahirrahmanirrahim:
Allah (swt) 's rays of light of the heavens and the earth.
The example of Allah (swt) 's rays 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.
Rays upon rays.
Allah (swt) guides to Allah (swt) light whom Allah (swt) wills.
And Allah (swt) presents examples for the people,
and Allah (swt) is Knowing of all things.
~Holy Al Qur'an Surah:An_Nur 24:35
