Qur'anic verses - The Nature of God:

The true contemplation can only spring from a heart that believes in the One True God and knows His nature. It is essential to establish a strong faith in God before embarking on any spiritual journey and to follow the Qur'anic guidance in this spiritual expedition.

Everything else: the beauty of the nature, the splendour of the universe, and whatever in the heavens and the earth are subjected to His absolute Laws.

To Him is due the primal origin of the heavens and the earth: When He decreeth a matter, He saith to it: "Be," and it is.
[Qur'an 2:117]
