it is he who keeps you alive in your sleep at night and knows all that you do during the day. he wakes you up from your sleep to complete your worldly life after which you will all return to him. he will let you know all about what you had done in your worldly life.
وهو الذي يتوفاكم بالليل ويعلم ما جرحتم بالنهار ثم يبعثكم فيه ليقضى أجل مسمى ثم إليه مرجعكم ثم ينبئكم بما كنتم تعملون
