"The world is more worthless than this dead lamb"

Messenger of Allah (S.A.W.S.) was passing through the bazaar with his Companions on his both sides, when he saw a dead skinny lamb.
He held its ear and said, "Who of you would like to have it for a dirham"
They replied, "We do not like to get it for nothing, and what shall we do with it?"
Then he (S.A.W.S.) asked, "Would you like to have it for nothing?"
They replied, "Had it been alive, it would have been defective because it is skinny; but when dead it is of no use"
Messenger of Allah (S.A.W.S.) said, "Truly, the world is more contemptible to Allah than this (the dead lamb) is to you".
[Muslim]

Commentary: This Hadith shows the futility of this world for which one struggles so madly throughout his life.
