The Darknesses of the Earth are Five

Let's suppose a small grain is in the darkness of the earth. The darkness of the earth is of five types. Let's say, a small grain is buried in mud at the bottom of the sea. The first darkness is that of the soil in which it is buried in. The second is the darkness of water in the sea. The third is the darkness of the night. The fourth is the darkness of the overcrowded clouds. The fifth is the darkness of the pouring rain. Five levels of darknesses above this small grain and Allah ﷻ knows it (this grain). He ﷻ says, {There is not a grain in the darkness of the earth or anything fresh or dry, but is written in a Clear Record.} [Al-An'ām: 59] It is written, clear, evident, and well-known with the Rabb ﷻ of al-'alamin (all created things).
