Hadith 4:166

Narrated Abu Huraira:

The Prophet said, "The example of a miser and the one who gives in charity, is like the example of two men wearing iron cloaks so tightly that their arms are raised forcibly towards their collar-bones. So, whenever a charitable person wants to give in charity, his cloak spreads over his body so much so that it wipes out his traces, but whenever the miser wants to give in charity, the rings (of the iron cloak) come closer to each other and press over his body, and his hands gets connected to his collar-bones. Abu Huraira heard the Prophet saying. "The miser then tries to widen it but in vain."
