And among His Signs is that He shows you the lightning for fear and for hope, and He sends down water (rain) from the sky, and therewith revives the earth after its death.

Then afterwards when He will call you by a single call, behold, you will come out from the earth (i.e. from your graves for reckoning and recompense).
