The Thunder - 13:12
He is the One who shows you lightning as fear and hope and forms heavy clouds.
Formation of heavy clouds and the role of clouds:
The Cow/2:164
In the creation of the heavens and the earth, and in the alternation of night and day, and in the ships that sail in the ocean for the benefit of mankind, and in Allah sending down water from the sky and reviving the earth after its death, and in every kind of living creature He spreads therein, and in the winds and the swirling of the clouds between the sky and the earth, there are indeed signs (lessons and proofs) for a people who use their reason.
The Heights/7:57
It is He who sends the winds as a foretaste of His mercy. We drive the heavy clouds over a dead land after they are gathered and loaded. We send down with it water and bring forth with it all kinds of crops. Thus do We bring forth the dead. Perhaps from this you may take an admonition.
The Rocky Tract/15:22
We sent the wind as an instiller, and We sent down water from the sky and watered you with it, but you could not store it.
The Light/24:43
Do you not know that Allah drives the clouds, then He gathers them together, then He piles them one upon another and you see the rain coming out of them? He sends down hail from the sky in great masses, and He causes it to fall on whom He wills, and He keeps it away from whom He wills, and the flash of His lightning is almost eye-catching.
The Romans/30:48
Allah sends the winds to drive the clouds, and He spreads them in the sky as He wills, and you see the rain coming out of them. When He sends it down on whom He wills of His servants, they rejoice.
Originator/35:9
Allah is He Who sends the winds that stir the clouds. Then We drive them over a dead land, and We bring it back to life after its death. So is the resurrection.
