A close examination of the system and composition of every part of the categories of the universe, and their connection with each other, reveals that both parts of the universe and the universe as a whole are created by One, Omniscient, Omnipotent and All-Wise Creator.
Indeed, the formation of the parts of a tree, the parts of the body of an animal and its strength, their connection with each other, their connection with the Earth and the sun, the connection of the solar system with other solar systems and the galaxy, in one sentence is: Verily, from the composition of an atom and what goes on around it to the composition of the sun and the galaxies, reveal that the Creator of all is One: And He it is Who is God in the heavens and God in the earth; and He is the Wise, the Knowing.
[^3] men! Serve your Lord Who created you and those before you so that you may guard (against evil). Who made the earth a resting place for you and the heaven a canopy and (Who) sends down rain from the cloud then brings forth with it subsistence for you of the fruits; therefore do not set up rivals to Allah while you know.
[^4] Fifth Proof Imam al-Sadiq (as) was asked, “Why is it not permissible that there be more than one creator of the universe?” Thus, he (as) replied: …Furthermore, if you claim that there are two gods, there must be a division between them both, which has always existed, and that division would have to be a third god. However, if you claim that there are three gods, then there must be two divisions between them, leaving us with five gods, and so on ad aeternum.
[^5] Sixth Proof The Commander of the Faithful (as) said to his son al-Hasan (as): Beware, O son that if your Lord had an associate then his messengers would have certainly come to you and you would have seen signs of his sovereignty and dominion. You would have learnt his actions and attributes. However, He is One God like He has described Himself.
[^6] The outcome of the faith in Oneness of Allah, the Exalted, is His Unity of Service, because other than Him do not deserve service and cannot attain it. As everything and everyone other than Him is His servant: There is no one in the heavens and the earth but will come to the Beneficent Allah as a servant. [^7] Furthermore, service to other than Allah, the Exalted, is humiliation from the humiliated and begging from the needy.
In fact, it is humiliation even for humility and is begging from the need itself. O men!
