(Verily! In the creation of the heavens and the earth, and in the alternation of night and day, and the ships which sail through the sea with that which is of use to mankind,and the water( rain) which Allah sends down from the sky and makes the earth alive therewith after its death, and the moving ( living) creatures of all kinds that He has scattered therein, and in the veering of winds and clouds which are held between the sky and the earth, are indeed (Ayat(proofs) evidences, signs,etc for people of understanding)
This verse is one of the great verses in Quraan and Prophet Mohammad ordered us to think deeply about their meaning.
Here we will concentrate on the scientific commentary in what Allah said:" And in the alternation of night and day" to discover a botanical miracle in the former verse.
The importance of daytime for the continuous of life on earth:
Daytime, sunlight and its heat and radiations are the most important factors which Allah subjected so life can continue on our planet. Thu, when green plants are exposed to sunlight it transfers the energy of light into a chemical energy formed as bonds in the sugar substances this process is called "photosynthesis" also water and carbon dioxide are important components in this process. Photosynthesis is the basic source of almost all energies on earth and food substances, and if it hadn't been for light this process wouldn’t exist and all means of life would vanish.
The importance of night for the continuous of life:
Even thought most of the important biological processes take place in daytime, millions of them are at night. Scholars divided photosynthesis reactions into: light reactions which happen only in the existence of light, dark reactions which take place at night and doesn’t need light.
The alternation and its effect on life:
The differentiation between daytime and night in length, brightness and darkness, warmth and coldness are important factors for life. For instance, in flowering plants neither fruits nor seeds will grow if flowers haven’t, and these flowers don’t grow on any plant unless it has a chemical biological substance called" flowering hormone" which leads to the flowering process. This substance is formed only by the alternation of light and dark and their intensity and length; in fact God has created in the kingdom of plant those which need daily darkness until they flower, thus they are called" long night plants" on the contrary, there are others which need light" long daytime plants"
So according to these facts long night plants cant be moved to an environment where daytime is longer than night, therefore the plant will not have flowers, fruits nor seeds this happens if night plants are exposed to artificial light by using big mirrors to change dark into light in some parts of the earth, as a result the biological process of the plant will be disturbed.
There are some creatures; other than plants; that are affected by light and dark like some germs and sea plants.
It has been found that the ozone layer protects earth creatures from getting exposed to intense light so they won't get killed, in fact the increase of light resulted in the decrease of protein 20% from the rate in some plants, and this indicates that night is essential for their living.
From the above we realize that night is very important for life to continue. When I searched in the Quran for verses mentioning day and night, I have found that the word " night" comes before day in most of them which means that night is important as daytime, and the difference between them in length of time in important from a scientific view.
People who deny what Allah says in Quran have to prove it, and after all what has been mentioned can anyone assume that the creation of the universe is just a coincidence! As the Darwin and secular claims?!
We can only have faith that Allah al Mighty created everything under a decree.
