“ Like many who have been bred in poverty and have afterwards suddenly come into great wealth, the Arabs behaved as though their wealth was inexhaustible: each governor bought his appointment from the state and it became a recognised custom for him to exact a cash payment from the outgoing governor, and then he was free to raise what he could from his defenceless subjects to prepare for the day when his opportunities of exaction came to an end. The thoroughly unsatisfactory condition of the 'Umayyad financial system was one of the leading causes of their fall. ”
