If the sun did not set...

If the sun did not set, people would have no rest or comfort though their need for rest and comfort is absolutely essential for the calmness of their bodies and the relaxation of their senses, besides the facilitation of an easy digestion and the transport of energy to the organs. And if night did not come, greed would cause people to continue working to gather more wealth and that would harm their bodies and health. The perpetual sunshine heats the earth, and all the animals and plants on it.

Allah the Almighty has, therefore, ordained with His wisdom that the sun should shine for a period and set for a period like a lamp that is lit for sometime so that a household can carry out their needs and is then extinguished for sometime so that they can rest and calm down. Light and darkness are opposite to each other and yet both are made subservient to the interests of the worlds betterment and amelioration.

The four seasons Then think of the states of the sun that make the four seasons of the year and the wisdom and advantages therein! In the winter, heat comes back to the trees and plants, and the materials for fruits are formed. Air (humidity) is condensed to make clouds and rains. The bodies of animals grow and become stronger. In the spring, the materials that have been formed in the winter appear and plants grow and bloom. Animals become excited and ready for copulation.

In the summer, the air becomes hot and fruits ripen. The waste matters of bodies dissolve and the surface of the earth becomes dry and ready now for building and for other works. In the autumn, the air is fresh, diseases disappear, bodies are healthy, the night is long that it can be fit for some certain works due to its length, and the weather is nice for other advantages that to mention will take a lot of time.

Now consider the motion of the sun through the twelve Zodiacs to complete a year and the wisdom underlying it. This is the period that comprises the four seasons: winter, spring, summer, and autumn. Grains and fruits ripen during this annual movement of the sun to meet human needs. This cycle of development goes on continually. Do you not see that a year is the period of the movement of the sun from the Aries to the Aries?

With a year and its components time has been measured since ancient times and throughout all ages. People calculate thereby the periods of life-spans, loans, contracts and other business matters.
