Allah Subhanahu wa Ta'ala says (Qur'an Translation): And with Him (Allah) are the keys of the unseen (of which) none but He knows. And He knows what is in the land and in the sea. And there is not a leaf that falls but that He knows about it, and not a grain (seed) in the darkness of the earth, nor a thing alive (organic), or dry (inorganic) but that (it is noted) in a clear record. And He is the One Who takes your souls by night (when your are asleep), and has knowledge of all that you have done by day. And He brings you back to life each day that a term appointed (your life period) be fulfilled. And afterward unto Him is your return. Then He will proclaim unto you what you used to do. (Al-An'am 6: 59-60)
