According to Quranic verses and traditions, there are two broad spheres of creation. That is, the sphere of light and that of objects. Depending on the former, the sphere of light functions as the guide light for the sphere of objects. The first Divine creation was the existential light of the Prophet Muhammad, of which everything else appeared. It was the origin of the whole enterprise of creation, for which there have been other designations such as intellect, light, soul, and pen. The light of the Infallibles, i.e. Imam Ali, Lady Fatima, other Imams, the prophets and apostles, the Divine Throne, the Divine Table, the Paradise, and the souls of believers were all derived from the light of the Prophet Muhammad. In the sphere of objects, water was the first creation, which was ultimately from the light of the Prophet. Then the whole universe came into being within six days in the Divine scale of time.
