Surah An-Nur · Ayah 43

Do you not see that Allāh 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 lightning almost takes away the eyesight.
