How rain forms
remained a great mystery for a long time. Only after weather radar was
invented was it possible to discover the stages by which rain is formed.
According to
this, the formation of rain takes place in three stages. First, the "raw
material" of rain rises up into the air with the wind. Later, clouds are
formed, and finally raindrops appear.
The Qur'an's
account of the formation of rain refers exactly to this process. In one
verse, this formation is described in this way:
"It is God Who sends the winds which
stir up clouds which He spreads about the sky however He wills. He forms them
into dark clumps and you see the rain come pouring out from the middle of
them. When He makes it fall on those of His slaves He wills, they
rejoice" (The Qur'an, 30:48)
Now, let us
examine these three stages outlined in the verse more technically.
FIRST STAGE: “It
is God Who sends the winds..."
Countless air
bubbles formed by the foaming of the oceans continuously burst and cause
water particles to be ejected towards the sky. These particles, which are
rich in salt, are then carried away by winds and rise upward in the
atmosphere. These particles, which are called aerosols, function as water
traps, and form cloud drops by collecting around the water vapor themselves,
which rises from the seas as tiny droplets.
SECOND STAGE:
".... which stir up clouds which He spreads about the sky however He wills.
He forms them into dark clumps..."
The clouds are
formed from water vapor that condenses around the salt crystals or dust
particles in the air. Because the water droplets in these clouds are very
small (with a diameter between 0.01 and 0.02 mm), the clouds are suspended in
the air, and spread across the sky. Thus, the sky is covered in clouds.
The above illustration shows the water droplets being released into
the air. This is the first stage in the formation of rain. After that, the
water droplets in the newly formed clouds will be suspended in the air and
then condense to form rain. All of these stages are related in the Qur'an.
THIRD STAGE:
"…and you see the rain come pouring out from the middle of them"
The water
particles that surround salt crystals and dust particles thicken and form
raindrops, so, drops that become heavier than the air leave the clouds and
start to fall to the ground as rain.
As we have
seen, every stage in the formation of rain is related in the verses of the
Qur'an. Furthermore, these stages are explained in exactly the right
sequence. Just as with many other natural phenomena on the Earth, God gives
the most correct explanation of this phenomenon as well, and made it known to
people in the Qur'an centuries before it was discovered.
In another
verse, the following information is given about the formation of rain:
"Have you not seen how God drives along
the clouds, then joins them together, then makes them into a stack, and then
you see the rain come out of it? And He sends down from the sky mountain
masses (of clouds) with cold hail in them, striking with it anyone He wills
and averting it from anyone He wills. The brightness of His lightning almost
blinds the sight." (The Qur'an, 24:43)
Scientists
studying cloud types came across surprising results regarding the formation
of rain clouds. Rain clouds are formed and shaped according to definite
systems and stages. The formation stages of cumulonimbus, one kind of rain
cloud, are these:
1. STAGE, Being driven along: Clouds are carried along, that is, they are driven along, by the wind. 2. STAGE, Joining: Then, small clouds (cumulus clouds) driven along by the wind join together, forming a larger cloud. 3. STAGE, Stacking: When the small clouds join together, updrafts within the larger cloud increase. The updrafts near the centre of the cloud are stronger than those near the edges. These updrafts cause the cloud body to grow vertically, so the cloud is stacked up. This vertical growth causes the cloud body to stretch into cooler regions of the atmosphere, where drops of water and hail formulate and begin to grow larger and larger. When these drops of water and hail become too heavy for the updrafts to support them, they begin to fall from the cloud as rain, hail, etc.
We must
remember that meteorologists have only recently come to know these details of
cloud formation, structure and function, by using advanced equipment like
planes, satellites, computers etc. It is evident that God has given us a
piece of information that could not have been known 1,400 years ago.
Small clouds (cumulus clouds) are carried along and joined together by
the wind, that is, as the verse says: "…God drives along the clouds,
then joins them together …"
