A person considered a religious successor to the Islamic prophet Muhammad (Muhammad ibn ʿAbdullāh) and a leader of the entire Muslim community would have used what financial institution?
Bayt al-mal Bayt al-mal (بيت المال ) is an Arabic term that is translated as "House of money" or "House of Wealth." Historically, it was a financial institution responsible for the administration of taxes in Islamic states, particularly in the early Islamic Caliphate. It served as a royal treasury for the caliphs and sultans, managing personal finances and government expenditures. Further, it administered distributions of zakat revenues for public works. Modern Islamic economists deem the institutional framework appropriate for contemporary Islamic societies.
Muhammad Ahmad Muhammad Ahmad bin Abd Allah (Arabic: محمد أحمد ابن عبد الله; August 12, 1844 – June 22, 1885) was a religious leader of the Samaniyya order in Sudan who, on June 29, 1881, proclaimed himself the Mahdi, the messianic redeemer of the Islamic faith. His proclamation came during a period of widespread resentment among the Sudanese population towards the oppressive policies of the Turco-Egyptian rulers, and capitalized on the messianic beliefs popular among the various Sudanese religious sects of the time. More broadly, the Mahdiyya, as Muhammad Ahmad's movement was called, was influenced by earlier Mahdist movements in West Africa and other forms of Islamic revivalism that developed in reaction to the growing military and economic dominance of the European powers throughout the 19th century.
