Qur'an 39: 42 ...... Surely there are signs in this for those who think.

"It is Allah Who recalls the souls of men upon their death, and of the living during their sleep. He withholds the souls of those on whom He has passed the decree of death, and restores the rest till an appointed term. Surely there are signs in this for those who think." Qur'an 39: 42.
