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.
