Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "The slave of the dirham, the dinar and the cloak has perished. If he is given, he is pleased; and if he is not given, he becomes displeased. Such a slave has perished, and when a thorn pricks him, may he be unable to remove it."
