There is no God but Allah

The essence of Islam is to know of the existence of Allah, and to understand that there is no god but Allah. To practice Islam is to allow this truth to manifest itself in every aspect of one's life. Allah reveals this truth in the basic source of Islam, the Qur'an:

Most people think that matter, the underlying substance of the universe, has an absolute existence, and regard Allah as but an abstract idea. (Allah is truly beyond what they ascribe to Him) The truth is, however, only Allah truly exists, and the rest is merely His Creation.

The entire universe and everything in it was created by Allah. Before the Creation of the universe, nothing existed, in the material sense. It was all non-existence. At the moment when the universe was created, the Al-Awwal (The First) and Al-Akhir (The Last) Allah, Who is beyond all, created time, matter and space. In the Qur'an, Allah relates this matter as follows:

Allah holds everything under His control also after creating the matter. Everything happening, even at this very instant, is ordained by Allah. Every raindrop, each child that opens its eyes to the world, the process of photosynthesis in plants, all the bodily functions of living things, the courses of stars in far remote galaxies, each seed sprouting forth, or any other event that we might think of, or fail to think of, are all ordained by Allah. It is Allah Who creates all things. Every event occurs within His command:

Were the universe left to its own will, it would become disordered, scattered and corrupted. However, the perfect equilibrium in all things, from the cells of a living organism, to the stars in deep outer space, all reveal the existence of something that is controlling them at every moment, with the same perfection as their original Creation. In any corner of the universe, one will always come to recognize a flawless plan:

Denying that Allah is the Creator, and attributing divinity to that which He created, despite the abundance of proof to the contrary, is as nonsensical as claiming that a skyscraper was not built by construction workers, but came into being by the free will of bricks, or the placement of one on top of the other by pure coincidence.

The perfect order in the universe, and the supreme Creation of living things, reveals to us that they have all been created by a single Creator, in other words Allah created them. If there were other gods, that is, others capable of similarly ordaining their will, disorder and confusion would prevail. That there is no god but Him, and that no other being in the universe has any similar power, is related in a verse of the Qur'an as follows:

As stated in the verse above, there is no other god beside Him. He has no son. He is above such human attributes. We clearly understand from this verse that those religions claiming that Allah has a "son" are misguided. (Allah is beyond that) The Oneness of Allah is further emphasized in the Qur'an as follows:
