Answer:

Firstly: In the Fifteenth Word, through seven steps comprising seven irrefutable explanations, the truth underlying the verse

وَلَقَدْ زَيَّنَّا السَّمَاۤءَ الدُّنْيَا بِمَصَابِيحَ وَجَعَلْنَاهَا رُجُومًا لِلشَّيَاطِينِAnd indeed, We have adorned the nearest heaven with lamps and made them missiles against the devils. — The Qur’an 67:5.

—namely, that the spying devils are driven away and expelled from the heavens by means of the stars—is explained with such clarity that even the most obstinate materialist is convinced, silenced, and compelled to acknowledge it.

Secondly: In order to bring these three truths of Islam, which appear so remote, closer to the understanding of limited human intellects, we shall explain them by means of a comparison.

Imagine, for example, that the military department of a government is situated in the east of a country, the judicial department in the west, the educational department in the north, the scientific department in the south, and the civil administration in the centre.

Through wireless communication, telephone, and telegraph, each department receives information concerning matters within its area of responsibility in a perfectly orderly manner and is able to keep them under observation. Thus, it is as though the entire country were simultaneously a judicial department, while also being a military, administrative, and scientific department.

Likewise, it sometimes happens that different governments belonging to different states, each with its own capital, exercise their respective authority within a single country, whether through colonies, special privileges, or commercial relations.

Although the people and subjects are the same, each government maintains a relationship with them through its own particular privileges. The activities of these governments, though their centres are far apart, intersect with one another. In every house, as it were, they draw close together, and each has a share in the affairs of every individual.

Minor matters are dealt with within the smaller sphere to which they belong. Not every minor matter is brought before the great and general centre. Yet when such matters are discussed, they are described as though they had been dealt with directly in that greater sphere, because they are, in fact, governed by its laws. Thus, they are presented as though they had been subjects of discussion within that general sphere.

Just as in these two examples, so too is the realm of the heavens, although exceedingly distant as a capital and centre, connected with the hearts of human beings upon the earth, as though spiritual telephone lines extended to their hearts.

Moreover, the heavenly realm is not concerned solely with the physical world. Since it encompasses the ālam-i arwāhThe spiritual realm of souls and spiritual beings. (the world of spirits) and the ālam-i mithālThe immaterial realm in which the images of all existence and events are reflected. (the world of similitudes), it also, in a certain sense, envelops the ālam-i shahādahThe visible world; the realm of physical existence that is perceptible to the senses. (the visible world), as though from behind a veil.
