Yahya related to me from Malik from Yahya ibn Said that he had heard that Abdullah ibn Abbas said, "Stealing from the spoils does not appear in a people but that terror is cast into their hearts. Fornication does not spread in a people but that there is much death among them. A people do not lessen the measure and weight but that provision is cut off from them. A people do not judge without right but that blood spreads among them. A people do not betray the pledge but that Allah gives their enemies power over them."

Muwatta Malik Book 21, Hadith 28
