Blasphemy of a Muslim

Why would universe express its sadness. If there is ever sadness in the world and the universe, what probable reason would it be. And how the universe express its sadness. Definitely through some sad songs sung by humanity that is the best creation of this universe. For me any sadness expressed by me and the world and the universe has to have an origin. What should be my point of reference, where all my pain and sadness be meaningless and would actually be about something more purposeful and thereby it would make any sense, because I am far from a sad perosn.
Mostly I laugh a lot but what would be the reason for my sadness behind all the laughter.
