Conclusion

It is of the utmost importance to understand correctly the secret beyond matter explained in this chapter. Mountains, plains, flowers, people, seas—briefly everything we see and everything that God informs us in the Qur'an that exists and that He created out of nothing is created and does indeed exist. However, people cannot see, feel or hear the real nature of these beings through their sense organs. What they see and feel are only their copies that appear in their brains. This is a scientific fact taught at all schools of medicine. The same applies to the book you are reading now; you can not see nor touch the real nature of it. The light coming from the original book is converted by some cells in your eyes into electrical signals, which are then conveyed to the visual center in the back of your brain. This is where the view of this book is created. In other words, you are not reading a book which is before your eyes through your eyes; in fact, this book is created in the visual center in the back of your brain. The book you are reading right now is a “copy of the book” within your brain. The original book is seen by God.

It should be remembered, however, that the fact that the matter is an illusion formed in our brains does not "reject" the matter, but provides us information about the real nature of the matter: that no person can have connection with its original. Moreover, the matter outside is seen not just by us, but by other beings too. The angels God delegated to be watchers witness this world as well:

And the two recording angels are recording, sitting on the right and on the left. He does not utter a single word, without a watcher by him, pen in hand! (Surat Qaf, 17-18)

Most importantly, God sees everything. He created this world with all its details and sees it in all its states. As He informs us in the Qur'an:

… Heed God and know that God sees what you do (Surah al-Baqara, 233)

Say: "God is a sufficient witness between me and you. He is certainly aware of and sees His servants." (Surah al-Isra', 96)

It must not be forgotten that God keeps the records of everything in the book called Lawh Mahfuz (Preserved Tablet). Even if we don't see all things, they are in the Lawh Mahfuz. God reveals that He keeps everything's record in the "Mother of the Book" called Lawh Mahfuz with the following verses:

It is in the Source Book with Us, high-exalted, full of wisdom. (Surat az-Zukhruf, 4)

… We possess an all-preserving Book. (Surah Qaf, 4)

Certainly there is no hidden thing in either heaven or Earth which is not in a Clear Book. (Surat an-Naml, 75 )

They said, 'Glory be to You!;
We have no knowledge except what You have taught us.
You are the All-Knowing, the All-Wise.'
(Surat al-Baqara, 32)
