Volume 7, Book 72, Number 689:
Narrated Abu Huraira:
Allah’s Apostle has set forth an example for a miser and a charitable person by comparing them to
two men wearing two iron cloaks and their hands are raised to their breasts and necks. Whenever
the charitable man tries to give a charitable gift, his iron cloak expands till it becomes so wide that it
will cover his fingertips and obliterate his tracks And, whenever the miser wants to give a charitable
gift, his cloak becomes very tight over him and every ring gets stuck to its place Abu Huraira added; I
saw Allah’s Apostle putting his finger in the (chest) pocket of his shirt like that If you but saw him
trying to widen (the opening of his shirt) but it did not widen
