For this reason did We prescribe to the children of Israel that whoever slays a soul, unless it be for manslaughter or for mischief in the land, it is as though he slew all men; and whoever keeps it alive, it is as though he kept alive all men; and certainly Our messengers came to them with clear arguments, but even after that many of them certainly act extravagantly in the land.

Allah takes the souls at the time of their death, and those that die not during their sleep; then He withholds those on whom He has passed the decree of death and sends the others back till an appointed term; most surely there are signs in this for a people who reflect.
