It is narrated that (angel) Izraeel (AS) came to take the life of Prophet Noah (AS). Noah (AS) asked:

Can you allow me to move from sunshine to a shade? Izraeel (AS) replied: Yes. Then Prophet Noah (AS) said: Whatever happened to me in life was equal to the time it took me to move from sunshine into shade [2]. Imam Baqir (AS) said: Consider the world as an abode which you are staying in and then you pack and go; or consider it like wealth which you have found in your dreams and when you wake up you cannot see it. Because according to wise people and those who know God, world is like movement of shades [2].
