In one verse of the Qur'an, the "fecundating" characteristic of the winds,
and the formation of rain as a result are mentioned.
In this verse, it is pointed out that the first stage in the formation of rain is
wind. Until the beginning of the 20th century, the only relationship between
the wind and the rain that was known, was that the wind drove the clouds.
However, modern meteorological findings have demonstrated the
"fecundating" role of the wind in the formation of rain.
This fecundating function of the wind works in the following way:
On the surface of oceans and seas, countless air bubbles form because of
the water's foaming action. The moment these bubbles burst, thousands of tiny
particles, with a diameter of just one hundredth of a millimeter, are thrown up
into the air. These particles, known as "aerosols", mix with dust carried from
the land by the wind, and are carried to the upper layers of the atmosphere.
These particles carried to higher altitudes by winds come into contact with
water vapour up there. Water vapour condenses around these particles and
turns into water droplets. These water droplets first come together and form
clouds, and then fall to the Earth in the form of rain.
As seen, winds "fecundate" the water vapour floating in the air with the
particles they carry from the sea, and eventually help the formation of rain
clouds.
If winds did not possess this property, water droplets in the upper
atmosphere would never form, and there would be no such thing as rain.
The most important point here is that this critical role of the wind in the
formation of rain was stated centuries ago in a verse of the Qur'an, at a time
when people knew very little about natural phenomena
