And He is the One who sends down water (rain) in due measure from the sky, to revive dead lands therewith, and even so you will be brought forth (from the graves). (Qur’an, 43:11)

RAIN is one of the gifts of God to man. In the verse above, God says that the rain has its own mathematics and that it is sent according to “due measure.” Water on earth is subject to an impeccable process and passes in due order from the state of liquid to the state of gas and solid. It has a marvelous balancing power, as it balances energy while satisfying the vital needs of the living being.

You would not have gotten an answer if you were, a century back, to ask a scientist whose field of interest was rainfall in particular, “Is there a measure in the rainfall; can it be quantified?” Being ignorant of the meteorological phenomena going on in every part of the world, the scientist would not have been in a position to say anything on the issue.

The Qur’an told us 1,400 years ago that the rainfall had a certain measure. Research conducted in the last century revealed the process of rainfall, shedding light over the cyclical characteristics of water. One of the facts discovered was that the earth’s annual rainfall was always of the same amount. The amount per second varied between 16-17 million tons. Thus, the amount of rain falling was above 500 trillion tons a year while an equal amount evaporated.

These yearly values remain constant. This constancy was of great significance in establishing the ecological balance of the world. The scientist of a few centuries back could not have estimated the amount of the rainfall in the region where he lived since the precipitation yearly changed according to region. He might have concluded, therefore, that rain is not quantifiable.

Calculations related to water cycle
The rainfall and cycle of water involve complicated calculations. To give you an example, researchers were curious to know the reason for the maximum temperature of the upper portion of the tropical ozone layer which was maximum 28 degrees Celsius, despite the sun’s continual warming of the water. Their research produced the following finding: the factor that prevented the overheating of the ozone layer in warmer regions was not merely water vapor, but at the same time the shadow cast by clouds. In the shade, the temperature dropped.

The shield prevented the earth from overheating. Water vapor also exerts a greenhouse effect. Along with carbon dioxide, methane and other gases, it creates an invisible insulation layer in the atmosphere. This layer prevents the totality of every radiation coming down on earth under normal conditions from getting lost in the space where cold is reigning. Water vapor forms 60 percent of the “natural greenhouse effect,” making the basic climate of the earth relatively warm.

All these things are finely calculated; we can gain an insight into this if we examine the greenhouse clouds revolving around the planet Venus. The dense clouds muffle it, so that only half of the sun’s rays reach it.

The quantity of 97 percent carbon dioxide there creates a super greenhouse effect and the temperature rises up to 500 degrees Celsius. This temperature far exceeds the temperature range in which man can live.

The water cycle on earth, passing through the states of liquid, cloud and water vapor, is calculated with precision. In contradistinction with the general properties of water, the clouds do not freeze, even at a temperature of – 30 degrees Celsius.

As it is stated in the Qur’an, there are masses of clouds as large as mountains, but they do not freeze into mountains of ice to fall upon the earth. Had it not been for this precise calculation in the formation of clouds and the rainfall and for the ideal arrangement of the chemical composition of water by its Creator, the system would certainly not function.

When we throw an object of a few kilograms from a balcony, we can follow its descent. If we empty a large pan full of water from the balcony, we can observe the splash on the ground.

The fall of tons of water from above, thanks to God’s programming, is so arranged that water coming down in drops from above is a blessing rather than a natural disaster.

This is the wonderful artistry in the physical rules imposed by God. Such a balancing of acceleration is definable in physical formulas. This definability, this calculation is due to God’s creation of rain in “due measure.”

Rain is life
In the same verse, God speaks of the rain’s regenerative power. It is a well-known fact that dry land is revitalized by rain and the vegetation becomes lush once again. The basic element of the animate being is DNA in which the hydrogen bonds keep changing, perpetuating life.

This hydrogen is exchanged with the hydrogen that emerges during the ionization of water. A dehydrated living being is like a frozen skeleton even though it may preserve its DNA and genetic code; it cannot reproduce or move. Only when the water comes up and lends the hydrogen from its disintegrated ions can the code be activated. Such characteristics can be observed in living microorganisms like microbes.
The more developed living beings cannot recover their vitality when fresh water is supplied, as their tissue surfaces have already deteriorated. Rain is thus the source of regeneration of plants and bacteria.

The last sentence of the verse that reads: “Similarly you will be raised (brought forth from the graves)” evokes the following association in our mind: God sends down rain in predetermined amounts, by which plants and bacteria that are near death are resuscitated.

The rising of man from the dead is no problem for God, Who knows the measure of all things.

God, who devised the system of regeneration of plants and bacteria through a well-calculated amount of rain, will raise man from the dead according to the measures and knowledge in His wisdom.

The sprouting of vegetation from the dead soil is something our eyes behold. What we see is the evidence of the facility with which our Creator will re-create His creation whose measure, calculation and formula are known only to Him.
