The Scientific Miracles in the Holy Qur’an (4)

G) The Qur’an on Clouds:
Scientists have studied cloud types and have realized that rain
clouds are formed and shaped according to definite systems and
certain steps connected with certain types of wind and clouds.
One kind of rain cloud is the cumulonimbus cloud. Meteorologists
have studied how cumulonimbus clouds are formed and
how they produce rain, hail, and lightning.
They have found that cumulonimbus clouds go through the
following steps to produce rain:
1) The clouds are pushed by the wind: Cumulonimbus clouds
begin to form when wind pushes some small pieces of clouds
(cumulus clouds) to an area where these clouds converge (see
figures 17 and 18).

zone near the horizon, where we can see a large cumulonimbus cloud. (Clouds and
Storms, Ludlam, plate 7.4.)

2) Joining: Then the small clouds join together forming a larger
cloud (see figures 18 and 19).

Figure 19: (A) Isolated small pieces of clouds (cumulus clouds). (B) When the small
clouds join together, updrafts within the larger cloud increase, so the cloud is stacked
up. Water drops are indicated by. (The Atmosphere, Anthes and others, p. 269.)

3) Stacking: When the small clouds join together, updrafts
within the larger cloud increase. The updrafts near the center
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 (see figures 19 (B), 20, and 21). 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

After the
cloud is stacked up,
rain comes out of it.
(Weather and Climate,
Bodin, p.123.)








God has said in the Qur’an:
{ Have you not seen how God makes the
clouds move gently, then joins them together,
then makes them into a stack, and then you
see the rain come out of it....} (Qur’an, 24:43)
Meteorologists have only recently come to know these details
of cloud formation, structure, and function by using advanced
equipment like planes, satellites, computers, balloons, and other equipment, to study wind and its direction, to measure humidity
and its variations, and to determine the levels and variations of
atmospheric pressure.

The preceding verse, after mentioning clouds and rain, speaks
about hail and lightning:
{....And He sends down hail from mountains
(clouds) in the sky, and He strikes with it
whomever He wills, and turns it from whomever
He wills. The vivid flash of its lightning
nearly blinds the sight. } (Qur’an, 24:43)
Meteorologists have found that these cumulonimbus clouds,
that shower hail, reach a height of 25,000 to 30,000 ft (4.7 to 5.7
miles), like mountains, as the Qur’an said: {And He sends
down hail from mountains (clouds) in the sky} (see figure 21).

 Figure 21: A cumulonimbus cloud. (A Colour Guide to Clouds, Scorer and Wexler, p.23.)

This verse may raise a question. Why does the verse say “its
lightning” in a reference to the hail? Does this mean that hail is
the major factor in producing lightning? Let us see what the book
entitled Meteorology Today says about this. It says that a cloud
becomes electrified as hail falls through a region in the cloud of
supercooled droplets and ice crystals. As liquid droplets collide
with a hailstone, they freeze on contact and release latent heat.
This keeps the surface of the hailstone warmer than that of the
surrounding ice crystals. When the hailstone comes in contact
with an ice crystal, an important phenomenon occurs: electrons
flow from the colder object toward
the warmer object. Hence, the
hailstone becomes negatively
charged. The same effect
occurs when supercooled
droplets come in contact
with a hailstone and tiny
splinters of positively
charged ice break off.
These lighter positively
charged particles are then
carried to the upper part of
the cloud by updrafts. The
hail, left with a negative
charge, falls towards the
bottom of the cloud, thus the
lower part of the cloud becomes
negatively charged. These negative
charges are then discharged as lightning. We conclude from this
that hail is the major factor in producing lightning.
This information on lightning was discovered recently. Until
1600 AD, Aristotle’s ideas on meteorology were dominant. For
example, he said that the atmosphere contains two kinds of exhalation,
moist and dry. He also said that thunder is the sound of the
collision of the dry exhalation with the neighboring clouds, and
lightning is the inflaming and burning of the dry exhalation with a thin and faint fire. These are some of the ideas on meteorology
that were dominant at the time of the Qur’an’s revelation, fourteen
centuries ago.
