The Quran 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.

Small pieces of clouds (cumulus clouds) moving towards a convergence 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.

(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. 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.

Let's see what ALLAH has said in Quran Majeed:

"Have you not seen how ALLAH 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),2 like mountains, as the Qur’an said: 

“...And He sends down hail from mountains (clouds) in the sky..."
