What did the Prophet Muhammad (peace be upon him) illustrate through his example of the miser and the generous person?
      Narrated Abu Huraira:                          Allah's Apostle said, The example of a miser and a generous person is      like that of two persons wearing iron cloaks from the breast upto the      neck When the generous person spends, the iron cloak enlarges and      spread over his skin so much so that it covers his fingertips and      obliterates his tracks. As for the miser, as soon as he thinks of      spending every ring of the iron cloak sticks to its place (against his     body) and he tries to expand it, but it does not expand. The Prophet      pointed with his hand towards his throat.
