It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Seek refuge in Allah from greed that leads to rust and blemish (upon the heart), from greed for what cannot be attained, and from greed that leads where there is nothing to hope for."
