Riyad-us-Saliheen 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."
