God

A man once asked Imaam Ja’far al-Saadiq:

((Why is it not possible for the Creator of the universe to be more than one? The Imaam replied: The fact that you claim God is two can be that they both have always been in existence and are powerful; or that they are both incapable; or that one is more powerful than the other. If both have the power, why does one not compete with the other so that He can be the only God? If one is powerful and the other is not, it is obvious that God is one and that is the Powerful One. As we witness the perfect organisation of the universe, the circulation of earth, the passing of day and night with the rising and setting of the sun and the moon, we have an absolute reason that its regulator is One.)).

With his delicate reasoning, Imaam Redhaa convinced a person, who believed in dualism, of the existence of the one God. The Imaam replied:

((To say that God is two is itself proof that He is One because until you have proof of the first, you cannot pursue the second. In the first, we both believe, in the second we disagree.)).
