Parables, Rain storm from the sky

Or [it is] like a rainstorm from the sky within which is darkness, thunder and lightning. They put their fingers in their ears against the thunderclaps in dread of death. But Allāh is encompassing¹ of the disbelievers.

The lightning almost snatches away their sight. Every time it lights [the way] for them, they walk therein; but when darkness comes over them, they stand [still]. And if Allāh had willed, He could have taken away their hearing and their sight. Indeed, Allāh is over all things competent.
