Quran 6.60-61
He it is Who gathereth you at night and knoweth that which ye commit by day. Then He raiseth you again to life therein, that the term appointed (for you) may be accomplished. And afterward unto Him is your return. Then He will proclaim unto you what ye used to do. He is the Omnipotent over His slaves. He sendeth guardians over you until, when death cometh unto one of you, Our messengers receive him, and they neglect not.
