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
