The Almighty said:
{And the heaven is opened and will become gateways. And the mountains are moved and will become a mirage}1.
Then, from the substances of their lights, a Third Universe was affected (Infa'ala)2, which is the Four Elements. So from it appeared: Fire, Air, Water, and Earth. And it mixed from their separated parts, so from that was the existence of the Human World and the rest of the existing universes.
