Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Beware of oppression, for oppression will be darkness upon darkness on the Day of Resurrection. And beware of miserliness, for miserliness destroyed those before you. It led them to shed each other's blood and to make lawful what was forbidden to them."
