It is evident that "the fact of creation", which reveals itself in every aspect of the universe, cannot be an outcome of the universe itself. For example, a bug could not have created itself. The solar system could not have created or organised itself. Neither plants, humans, bacteria, erythrocytes (red-blood corpuscles), nor butterflies could have created themselves. The possibility that these all could have originated "by chance" is not even imaginable.

Still others have heard that in the Qur’an it is written that Allah is "everywhere" but they cannot perceive what this exactly means. They tacitly think that Allah surrounds everything like radio waves or like an invisible, intangible gas.

However, this notion and other beliefs that are unable to make clear "where" Allah is (and maybe deny Him because of that) are all based on a common mistake. They hold a prejudice without any grounds and then are moved to wrong opinions of Allah. What is this prejudice?

The "external world" presented to us by our perceptions is merely a collection of the electrical signals reaching our brain. Throughout our lives, these signals are processed by our brain and we live without recognising that we are mistaken in assuming that these are the original versions of matter existing in the "external world".  We are misled because we can never reach the matter itself by means of our senses.

Bundles of light coming from an object fall on the retina upside-down. Here, the image is converted into electrical signals and transmitted to the centre of vision at the back of the brain. Since the brain is insulated from light, it is impossible for light to reach the centre of vision. This means that we view a vast world of light and depth in a tiny spot that is insulated from light.

Stimulations coming from an object are converted into electrical signals and cause an effect in the brain. When we "see", we in fact view the effects of these electrical signals in our mind.

What is it that separates real life and the dreams from one another? Ultimately, both forms of life are brought into being within the brain. If we are able to live easily in an unreal world during our dreams, the same thing can equally be true for the world we live in. When we wake up from a dream, there is no logical reason for not thinking that we have entered a longer dream that we call "real life". The reason we consider our dream to be fancy and the world as real is nothing but a product of our habits and prejudices.

All the images we view in our lives are formed in our centre of vision at the back of our brain, which makes up only a few cubic centimetres of the volume of the brain. Both the book you are now reading and the boundless landscape you see when you gaze at the horizon fit into this tiny space. Therefore, we see objects not in their actual size existing outside, but in the size perceived by our brain.
Dreams may be as realistic as real life. A person may even experience emotions and get excited in his dream in a genuine way not distinguishable from real life.
It is Allah Who sustains the heavens and the earth, lest they cease (to function): and if they should fail, there is none - not one - can sustain them thereafter: Verily He is Most Forbearing, Oft-Forgiving. (Surah Fatir, 41)
Allah! There is no god but He,-the Living, the Self-subsisting, Eternal. No slumber can seize Him nor sleep. His are all things in the heavens and on earth. Who is there can intercede in His presence except as He permitteth? He knoweth what (appeareth to His creatures as) before or after or behind them. Nor shall they compass aught of His knowledge except as He willeth. His Throne doth extend over the heavens and the earth, and He feeleth no fatigue in guarding and preserving them for He is the Most High, the Supreme (in glory). (Surat al-Baqara, 255)
To Allah belong the east and the West: Whithersoever ye turn, there is the presence of Allah. For Allah is all-Pervading, all-Knowing. (Surat al-Baqara, 115)
Fair in the eyes of men is the love of things they covet: Women and sons; Heaped-up hoards of gold and silver; horses branded (for blood and excellence); and (wealth of) cattle and well-tilled land. Such are the possessions of this world's life; but in nearness to Allah is the best of the goals (to return to). (Surat Aal-e Imran, 14)
But to Allah belong all things in the heavens and on earth: And He it is that encompasseth all things. (Surat an-Nisa, 126)
