Economic thought of Abu Ubaid reflects the significance of maintaining the society’s rights and obligations, making justice a central principle in running the government and building a sense of unity and shared responsibility. Abu Ubaid also explicitly states that the government is obliged to provide an adequate standard of living for every individual in a Muslim society. He said that state revenue (fai ', khumus, alms and zakat) have to be managed by the state and allocated to the community. In term of monetary, he states that the money have to have intrinsict value, standard exchange rate and medium of exchange.
