The financial requirements of Mahomet's state were of the simplest kind, for there is no trace of any form of governmental department having been instituted by him, even when he was master of the peninsula; nor can we name any permanent officials in his employ except his _muaddhin_ Bilal, and perhaps his court-poet Hassan. A staff of scribes was finally required both to take down his revelations and to conduct correspondence; but although he encouraged the acquisition of penmanship (indeed some of the prisoners at Badr are said to have been allowed to ransom themselves by teaching it to the Medinese), we know of no regular secretaries in his employ. As despot of Medina he combined the functions of legislator, administrator, general and judge; his duties in the last three capacities were occasionally delegated to others, as when he appointed a governor of Medina during his absence, or leaders for expeditions, with provision for successors in case of their falling, but we hear of no permanent or regular delegation of them. Till near the end of his career at Medina he maintained the principle that migration to that city was a condition of conversion; but when, owing to the extension of his power, this was no longer practicable, his plan was in the main to leave the newly converted communities to manage their internal affairs as before, only sending occasional envoys to discharge special duties, especially instruction in the Koran and the principles of Islam, and to collect the Alms; quite towards the end of his life he appears to have sent persons to the provinces to act as judges, with instructions to judge according to the Koran, and where that failed, _the practice_ (_sunna_), i.e. the practice of the community, for which a later generation substituted the practice of the Prophet. There were, therefore, no regular payments to permanent officials; and the taxation called _Alms_, which developed into an income-tax, but was at first a demand for voluntary contributions, was wholly for the support of the poor Moslems; it might not be used for the maintenance of the state, i.e. Mahomet and his family. For them, and for public business, e.g. the purchase of war material and gratuities to visitors, provision was made out of the booty, of which Mahomet claimed one-fifth (the chieftain's share had previously, we are told, been one-fourth), while the remainder--or at least the bulk of it--was distributed among the fighting men; the Prophet appears to have prided himself on the justice of his distribution on these occasions, and doubtless won popularity thereby, though we hear occasionally of grumbling; for difficulties occurred when a defeated tribe embraced Islam, and so could claim equality with their conquerors, or when portions of the spoil were irregularly employed by Mahomet to allay resentment: the persons whose allegiance was thus purchased were euphemistically termed "those whose
