Al-Mustawrid bin Shaddad said: "I was with the caravan of those who stopped with the Messenger of Allah (s.a.w) at a dead lamb. The Messenger of Allah (s.a.w) said: 'Do you think that this was insignificant to its owners when they threw it away?' They said:'Yes! It is because of its insignificance that they threw it away O Messenger of Allah!' He said: 'The world is more insignificant to Allah than this to its owners.'"
