Harbiy vazirlik qurolli kuchlarga oid barcha masalalarni o'z zimmasiga oladi, jumladan armiya, politsiya, qurol-yarog' jihozlari, harbiy materiallar, o'q-dorilar va shunga o'xshash masalalarni. Shuningdek, u harbiy akademiyalar, harbiy missiyalarni hamda armiya uchun zarur bo'lgan islomiy madaniyat va umumiy madaniyatdan kerakli narsalarni, urushga va unga tayyorgarlikka tegishli boshqa barcha narsalarni ham o'z ichiga oladi.

The War Department undertakes all issues related to the armed forces, whether they are the army, police, weapons equipment, war material, ammunitions or similar issues. They also include the military academies, military missions and whatever is needed of Islamic culture and general culture necessary for the army as well as anything else related to the war and preparation for it.

Bu ishlarning barchasi Harbiy vazirlik tomonidan amalga oshiriladi va nazorat qilinadi. Uning nomi urush va jangga bog'liqdir. Urush esa armiyani talab qiladi, armiya esa tayyorgarlik va shakllantirishni talab qiladi, shu jumladan uning shtab qo'mondonlari, ofitserlari va askarlarini.

All this is undertaken and supervised by the War Department. Its name is connected with warfare and fighting. Warfare requires an army and the army requires preparation and formation including its staff commanders, officers and soldiers.

Armiyaning o'z bayroqlari va tug'lari bor. Uning tuzilishi jismoniy va texnik mashg'ulotni talab qiladi, bunga zamonaviy texnika taraqqiyotiga muvofiq turli qurollardan foydalanib jang qilish usullarini o'rgatish ham kiradi. Shu sababli armiya harbiy-texnik bilim olishi va jang taktikasi hamda eng so'nggi turdagi barcha qurollardan foydalanish bo'yicha tayyorgarlikdan o'tishi shart.

The army has its flags and banners. Its formation requires training, both physical and technical, which includes training in the fighting techniques using various weapons, according to contemporary advancement in technology. Therefore, it is imperative for the army to undertake military and technical study and to acquire training in fighting tactics, and the use of all the latest variety all manner of weapononry.

Chunki armiya islomiy armiya bo‘lib, u Xalifalik davlatining armiyasi bo‘lsa, ya’ni dunyoga Islom da’vatini yetkazadigan armiya bo‘lsa, harbiy kuchlar uchun umuman islomiy madaniyatni, xususan urush qoidalari, tinchlik, sulh, shartnomalar va kelishuvlar bilan bog‘liq islomiy madaniyatni, barcha zarur tafsilotlari bilan birga egallashi zarurdir. Shu sababli, turli darajadagi barcha harbiy akademiyalar hamda harbiy missiyalar Urush vazirligi vakolatiga kiradi.

Since the army is an Islamic army and since it is the army of the Khilafah state which carries the Islamic Da’wa to the world, it is therefore imperative for the armed forces to acquire Islamic culture in general, and the specific Islamic culture related to the rules of fighting, peace, truces, treaties, agreements including all the detail required. Therefore, all military academies at various levels and military missions all fall under the mandate of the Department of War.

Qurolli kuchlar tarkibiga ichki xavfsizlik uchun mas'ul bo'linma, ya'ni politsiya ham kiritilishi kerak. Qurolli kuchlar ham, politsiya ham o'z vazifalarini bajarish uchun zarur bo'lgan barcha qurol, jihoz, ta'minot va zaruriy buyumlarga ega bo'lishi kerak. Shu sababli bu vazifalarning barchasi Urush vazirligi (Department of War) qaramog'iga kiradi.

The armed forces must include also a division that is in charge of internal security i.e. the police. Both the armed forces and the police should have all the weapons, equipment, supplies and the necessary provisions they need to carry out their duty. This is why all these tasks fall under the Department of War.
