It was narrated from Abu Hurairah that the Prophet said: "The parable of the miser and the one who gives in charity is that of two men wearing coats of mail with their hands tied to their collarbones. Every time the one who gives thinks of giving in charity, the (coat of mail) expands until it obliterates his traces, and every time the miser thinks of giving charity, every circle (of the coat of mail) contracts and sticks to him, and his hand is tied up to his collarbones." I heard the Messenger of Allah say: "He tries to expand it, but he cannot."
