Have you not seen that Allah is the One Who drives the cloud (first) gently, then joins its (various pieces) together, and then forms them into layers upon layers? Then you see that from spaces between them rain issues forth and falls down. And He sends down hail from the clouds (looking) like snow-covered mountains in the same sky (i.e. atmosphere). And then He throws it down upon whom He wills and turns it away from whom He likes. (Moreover, He creates lightning from the same clouds.) It seems as if the flash of the lightning (of clouds) would (dazzle their eyes and) snatch their sight away.
