Evidence of the Oneness of Allah includes the following: 1- The entire universe, in the way it is created and is controlled, testifies to the oneness of Allah. 2- The creation of the heavens and the earth, the alternation of night and day, the different kinds of inanimate objects, plants and fruits, the creation of humans and animals; all of that indicates that the Almighty Creator is One with no partner or associate. 3- The variety and greatness of these created things, the perfection of their formation, and the way they are maintained and controlled, all indicate that the Creator is One. 4- The soundness of the heavens and the earth, the order of the universe, the harmony among created things, all indicate that the Creator is One, with no partner or associate.

Tawhid al-Rububiyyah means affirming that Allah is One and Unique in His actions, such as creation, sovereignty, controlling affairs, provision, giving life and death, sending down the rain, and so on. A person’s Tawhid is not complete unless he affirms that Allah is the Lord, Sovereign, Creator and Provider of all things.
