´Mustawrid bin Shaddad said:` “I was riding with the Messenger of Allah (ﷺ) when he came across a dead lamb that had been thrown out.’ He said: ‘Don’t you think that this is worthless to its owners?’ It was said: ‘O Messenger of Allah, it is because it is worthless that they have thrown it out, - or words to that effect. He said: ‘By the One in Whose Hand is my soul, this world is more worthless to Allah than this is to its owners.’”
