allah, the exalted, says:

"but he who is greedy miser and thinks himself self-sufficient. and belies al-husna. we will make smooth for him the path for evil. and what will his wealth avail him when he goes down (in destruction)?'' (92:8-11)

"and whosoever is saved from his own covetousness, then they are the successful ones.'' (64:16)

563. jabir bin `abdullah (may allah be pleased with him) reported: messenger of allah (pbuh) said, "beware of oppression, for oppression will be darkness on the day of resurrection; and beware of stinginess because it destroyed those who were before you. it incited them to shed their blood and deem unlawful as lawful.''
