And it is He who sends the winds as good tidings before His
mercy until, when they have carried heavy rainclouds, We drive
them to a dead land and We send down rain therein and bring
forth thereby [some] of all the fruits. Thus will We bring forth the
dead; perhaps you may be reminded
And We have sent the fertilizing winds and sent down water
from the sky and given you drink from it. And you are not its
Modern science has affirmed the scientific points mentioned
in these verses of the Qur’an. The winds carry water particles
which are rich in salt up into the atmosphere. These particles
which are called “aerosols”, function as water traps and form
cloud drops by collecting around the water vapor themselves.
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.(1)
Thus, the sky is covered in clouds. 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.
Do you not see that Allah drives clouds? Then He brings them together, then
He makes them into a mass, and you see the rain emerge from within it. And
He sends down from the sky, mountains [of clouds] within which is hail, and He
strikes with it whom He wills and averts it from whom He wills. The flash of its
lightening almost takes away the eyesight.
Rain clouds are formed and shaped according to definite systems and stages.
The formation stages of cumulonimbus, a type of rain cloud, are:
Along: Clouds are
carried along, that
is, they are driven
along, by the wind.
Then, small clouds
driven along by the
wind join together,
forming a larger
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. 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.
A cloud becomes electrified as hail falls through a region in
the cloud of super-cooled 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
When the hailstone comes
in contact with an ice
crystal, an important phenomenon
flow from the colder
object toward the warmer
object. Hence, the hailstone
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 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
And the thunder exalts [Allah] with praise of Him – and the
angels [as well] from fear of Him – and He sends thunderbolts
and strikes therewith whom He wills while they dispute about
Allah; and He is severe in assault
And indeed, for you in grazing livestock is a lesson. We give
you drink from what is in their bellies – between excretion and
blood – pure milk, palatable to drinkers
Maurice Bucaille (3) said:
From a scientific point of view, physiological notions must be called upon to
grasp the meaning of this verse. The substances that ensure the general nutrition
of the body come from chemical transformations which occur along the
length of the digestive tract. These substances come from the contents of the
intestine. On arrival in the intestine at the appropriate stage of chemical transformation,
they pass through its wall and towards the systemic circulation. This
passage is effected in two ways: either directly, by what are called the ‘lymphatic
vessels,’ or indirectly, by the portal circulation. This conducts them first to the
liver, where they undergo alterations, and from here they then emerge to join the
systemic circulation. In this way, everything passes through the bloodstream.
The constituents of milk are secreted by the mammary glands. These are nourished,
as it were, by the product of food digestion brought to them via the
bloodstream. Blood therefore plays the role of collector and conductor of what
has been extracted from food, and it brings nutrition to the mammary glands,
the producers of milk, as it does to any other organ.
Here the initial process which sets everything else in motion is the bringing together
of the contents of the intestine and blood at the level of the intestinal wall
itself. This very precise concept is the result of the discoveries made in the chemistry
and physiology of the digestive system. It was totally unknown at the time
of Prophet Muhammad and has been understood only in recent times. I consider
that the existence in the Qur’an of the verse referring to these concepts can have
no human explanation on account of the period in which they were formulated.
