In the Holy Qur'an

Have not those who disbelieve known that the heavens and the earth were joined together as one united piece, then We parted them? And we have made from water every living thing. Will they not then believe? (21:30)

In the Traditions

Imam Jafar was asked by Mufaddal, "O My Master, there is a group of people that claim that this (creation) is the doing of nature (itself)", the Imam said, "Ask them about the nature, does it have knowledge and power to carry out such actions (as creation) or not? For if they answer that it has knowledge and power, then what is preventing them from acknowledging the existence of a creator? For verily, this is His creation. If they claim that nature does these actions without knowledge or without purpose while having witnessed the exactness and wisdom therein, it is (obviously) known that this is the work of a very wise creator, and what they have caleed 'nature' is the very system running through creation."
