Davlat xazinasi (Bayt ul-mol) — davlatning barcha daromadlari va musulmonlar haqli bo‘lgan barcha xarajatlari uchun mas’ul vakolatli idoradir. Shunday ekan, ilohiy qoidalarga ko‘ra musulmonlarga tegishli bo‘lgan, ammo egasi belgilanmagan, lekin sarflanish yo‘nalishi aniq bo‘lgan har qanday mol-mulk — yer, binolar, ma’danlar, pul yoki tovarlar — xazinaning huquqiy mulki hisoblanadi, u xazina ixtiyorida bo‘lsin yoki bo‘lmasin. Xuddi shunday, haqdorlar va haqiqiy egalariga sarflanishi lozim bo‘lgan, yoki musulmonlar va ularning ishlari manfaatlari yo‘lida, yoki Islom da’vatini olib borishga sarflanishi kerak bo‘lgan har qanday mablag‘ xazina zimmasidadir, bu mablag‘lar sarflangan bo‘lsin yoki bo‘lmasin. Demak, bu nuqtai nazardan xazina vakolatli idoradir.

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.
