In the time of Umar things changed. With each conquest, revenue increased. Umar also granted salaries to the army. Abu Huraira, the Governor of Bahrain, sent his revenue to Umar, amounting to five hundred thousand dirhams. Umar summoned a meeting of his Consultative Assembly and sought the opinion of the Companions about the disposal of the money. Uthman ibn Affan advised that the amount should be kept for future needs. Walid bin Hisham suggested that, like the Byzantines, separate departments of treasury and accounts should be set up.
