    THE WATER CYCLE

    In 1580, Bernard Palissy was the first man to describe the present day concept of water cycle. He described how water evaporates from the oceans and cools to form clouds. The clouds move inland where they rise, condense and fall as rain. This water gathers as lakes and streams and flows back to the ocean in a continuous cycle. In the 7th century B.C., Thales of Miletus believed that surface spray of the oceans was picked up by the wind and carried inland to fall as rain. In earlier times people did not know the source of underground water. They thought the water of the oceans, under the effect of winds, was thrust towards the interior of the continents. They also believed that the water returned by a secret passage, or the Great Abyss. This passage is connected to the oceans and has been called the Tartarus, since Platos time. Even Descartes, a great thinker of the eighteenth century, subscribed to this view. Till the nineteenth century, Aristotles theory was prevalent. According to this theory, water was condensed in cool mountain caverns and formed underground lakes that fed springs. Today, we know that the rainwater that seeps into the cracks of the ground is responsible for this. The water cycle is described by the Quraan in the following verses:

    Seest thou not that Allah Sends down rain from The sky, and leads it Through springs in the earth? Then He causes to grow, Therewith, produce of various Colours. [Al-Quraan 39:21]

    He sends down rain From the sky And with it gives life to The earth after it is dead: Verily in that are Signs For those who are wise. [Al-Quraan 30:24]

    And We send down water From the sky according to (Due) measure, and We cause it To soak in the soil; And We certainly are able To drain it off (with ease). [Al-Quraan 23:18]

    No other text dating back 1400 years ago gives such an accurate description of the water cycle.



    MOUNTAINS FIRMLY FIXED

    The surface of the earth is broken into many rigid plates that are about 100 km in thickness. These plates float on a partially molten region called aesthenosphere. Mountain formations occur at the boundary of the plates. The earths crust is 5 km thick below oceans, about 35 km thick below flat continental surfaces and almost 80 km thick below great mountain ranges. These are the strong foundations on which mountains stand. The Quraan also speaks about the strong mountain foundations in the following verse:

    And the mountains Hath He firmly fixed. [Al-Quraan 79:32]

    (*A similar message is contained in the Qur'aan in 88:19, 31:10 and 16:15)


    BARRIER BETWEEN SWEET AND SALT WATERS

    Consider the following Quraanic verses:

    He has let free the two bodies Of flowing water, Meeting together: Between them is a Barrier Which they do not transgress. [Al-Quraan 55:19-20]

    In the Arabic text the word barzakh means a barrier or a partition. This barrier is not a physical partition. The Arabic word maraja literally means they both meet and mix with each other. Early commentators of the Quraan were unable to explain the two opposite meanings for the two bodies of water, i.e. they meet and mix, and at the same time, there is a barrier between them. Modern Science has discovered that in the places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity and density. Oceanologists are now in a better position to explain this verse. There is a slanted unseen water barrier between the two seas through which water from one sea passes to the other.

    (Principles of Oceanography, Davis, pp. 92-93.)

    But when the water from one sea enters the other sea, it loses its distinctive characteristic and becomes homogenized with the other water. In a way this barrier serves as a transitional homogenizing area for the two waters. This scientific phenomenon mentioned in the Quraan was also confirmed by Dr. William Hay who is a well-known marine scientist and Professor of Geological Sciences at the University of Colorado, U.S.A. The Quraan mentions this phenomenon also in the following verse:

    And made a separating bar between the two bodies Of flowing water? [Al-Quraan 27:61]

    This phenomenon occurs in several places, including the divider between the Mediterranean and the Atlantic Ocean at Gibralter. But when the Quraan speaks about the divider between fresh and salt water, it mentions the existence of a forbidding partition with the barrier.

    It is He Who has Let free the two bodies Of flowing water: One palatable and sweet, And the other salty and bitter; Yet has He Made a barrier between them, And a partition that is forbidden To be passed. [Al-Quraan 25:53]

    Modern science has discovered that in estuaries, where fresh (sweet) and salt-water meet, the situation is somewhat different from that found in places where two seas meet. It has been discovered that what distinguishes fresh water from salt water in estuaries is a pycnocline zone with a marked density discontinuity separating the two layers. This partition (zone of separation) has salinity different from both the fresh water and the salt water.

    This phenomenon occurs in several places, including Egypt, where the river Nile flows into the Mediterranean Sea.



    PAIN RECEPTORS PRESENT IN THE SKIN

    It was thought that the sense of feeling and pain was only dependent on the brain. Recent discoveries prove that there are pain receptors present in the skin without which a person would not be able to feel pain. When a doctor examines a patient suffering from burn injuries, he verifies the degree of burns by a pinprick. If the patient feels pain, the doctor is happy, because it indicates that the burns are superficial and the pain receptors are intact. On the other hand if the patient does not feel any pain, it indicates that it is a deep burn and the pain receptors have been destroyed. The Quraan gives an indication of the existence of pain receptors in the following verse:

    Those who reject Our signs, We shall soon Cast into the Fire; As often as their skins Are roasted through, We shall change them For fresh skins, That they may taste The Penalty: for Allah Is Exalted in Power, Wise. [Al-Quraan 4:56]

    Prof. Tagatat Tejasen, Chairman of the Department of Anatomy at Chiang Mai University in Thailand, has spent a great amount of time on research of pain receptors. Initially he could not believe that the Quraan mentioned this scientific fact 1,400 years ago. He later verified the translation of this particular Quraanic verse. Prof. Tejasen was so impressed by the scientific accuracy of the Quraanic verse, that at the 8th Saudi Medical Conference held in Riyadh on the Scientific Signs of Quraan and Sunnah he proclaimed in public: There is no God but Allah and Muhammad (peace be upon him) is His Messenger.


    Can we find an explanation for the great universe? Is there any convincing interpretation of the secret of its existence? We realize that no family can function properly without a responsible head, that no city can prosperously exist without sound administration, and that no state can survive without a leader of some kind. We also realize that nothing comes into being on its own.

    Moreover, we observe that the universe exists and functions in the most orderly manner, and that it has survived perhaps billions of years. Can we, then, say that all this is accidental and haphazard? Can we attribute the existence of man and the whole world to a mere chance? Man represents only a very small portion of the great universe, and if he can make plans and appreciate the merits of planning, then his own existence and the survival of the universe must also be based on a planned policy.

    This means that there is a designing will behind our material existence, and that there is an extraordinary power to bring things into being and keep them moving in order. In the world there must be a great force in action to keep everything in order. In the beautiful nature there must be a Great Creator who makes these great pieces of art and produces everything for a special purpose in life.

    The deeply enlightened people recognize this Creator and call Him Allah. He is not a man because no man can create or make another man. He is not an animal, nor is He a plant. He is neither an idol nor is He a statue of any kind, because none of these things can make itself or create anything else. He is different from all these things, because He is the Maker and Keeper of them all. The maker of anything must be different and greater than the things that he makes.

    There are various ways to know Allah and there are many things to tell about Him. The great wonders and impressive marvels of the world are like open books in which we can read about Him. Besides, Allah comes to our aid through the many Messengers and Revelations He has sent down to humanity. These Messengers and Revelations tell us everything we need to know about our Creator.

    The complete acceptance of the teachings and guidance of our Creator as revealed to all His messengers (peace be upon him) is the religion of Islam. Islam enjoins faith in the oneness and sovereignty of Allah, which makes man aware of the meaningfulness of the universe and of his place in it. This belief frees the human being from all fears and superstitions as it makes him conscious of the presence of Allah Almighty, and of his obligation towards Him.

    This faith must be expressed and tested in action, for faith alone is not enough. Belief in one God requires that we look upon all humanity as one family under the universal omnipotence of the Creator, and Nourisher of all. Islam rejects the idea of a chosen people while on the other hand, it approves that belief in the Creator, and doing righteous deeds is the only way to Heaven. Thus, a direct relationship is established with Allah and without any intercessor at that.

    Islam is not a new religion. It is, in essence, the same message and guidance which Allah revealed to all His Prophets, like Adam, Enoch, Noah, Abraham, Ishmael, Isaac, David, Moses, Jesus and Muhammad (peace be upon him). But the message which was revealed to Prophet Muhammad (peace be upon him) is Islam in its comprehensive, complete and final form.

    The Qur'aan is the revealed words of Allah and the basic source of Islamic teachings and Laws. It deals with the basis of creeds, morality, history of humanity, worship, knowledge, wisdom, mans relationship with God, and human relationships in all aspects. It contains comprehensive teachings of which, can be built sound systems and social justice, economics, politics, legislation, jurisprudence, law and international relations, all of which are important contents of the Qur'aan.

    The hadeeth, which contains the teachings, sayings, approvals and actions of Prophet Muhammad (peace be upon him) meticulously reported and collected by his devoted companions, explains and elaborates on the Qur'aanic verses.
