1 The Bait ul- Mal and its Departments
The State Treasury (Bait-ul-Mal) is the competent authority in charge of all the State’s revenues and all the expenditures for which the Muslims are eligible. So every property, be it land, buildings, minerals, money, or merchandise for which the Muslims are entitled, according to the divine rules, but the person entitled for its ownership has not been designated though the area upon which it is spent is determined; such property would be a rightful property of Muslims’ Treasury, regardless of whether it is already in the sanctuary of the Treasury or not. Likewise, every property due to be spent upon its beneficiaries and rightful owners, or in the interests of the Muslims and their affairs, or in carrying the Islamic Daw’ah; all such funds area duty upon the treasury, regardless of whether the funds are spent or not. Therefore, the Treasury in this context, is the competent authority.
The Treasury is also a term used to describe the place where the funds which are the state’s revenues are kept and from which they are spent.
The first Treasury to be established, meaning the competent authority, was after the Revelation of Allah (swt) of the following verse: “They ask you about spoils of war. Say such spoils are at the disposal of Allah (swt) and the Messenger (saw): so fear Allah (swt) and keep straight the relations between yourselves, and obey Allah (swt) and His Messenger (saw) if you do believe.” [Al-Anfal: 1]
This was revealed in the wake of the battle of Badr, when the Muslims engaged in dispute over the spoils of war. Sa’eed Ibnu Jubair reported: I asked Ibnu Abbas regarding the Surah of Al-Anfal. He said: “It was revealed in Badr.” The spoils of Badr were the first funds the Muslims gained after the spoils of Abdullah Ibnu Jahsh expedition, Allah (swt) demonstrated the rule concerning their distribution. He made the spoils the property of the Muslims, and He commissioned the Messenger of Allah (saw) to dispose of them according to what he deemed in the best interest of the Muslims. So they were the property of the Treasury, to be disposed of by the guardian of the Muslims according to what he deemed in their best interest.
