Why Is Time So Important?

Time passes like the clouds. No matter how long man lives in this life, his life is short, as death is the end of every living creature. When Prophet Nuh (i.e. Noah) (Peace be upon him) was asked: "O the longest living prophet, how did you find this world?" He said: "It is like a house that has two doors. I entered from one of them and got out through the other."
