Idara ya Vita inashughulikia masuala yote yanayohusiana na majeshi ya kijeshi, iwe ni jeshi la nchi kavu, polisi, vifaa vya silaha, vifaa vya vita, risasi, au masuala mengine kama hayo. Pia inajumuisha vyuo vya kijeshi, misheni za kijeshi, na kila kinachohitajika katika utamaduni wa Kiislamu na utamaduni wa jumla unaohitajika kwa jeshi, pamoja na jambo lingine lolote linalohusiana na vita na maandalizi yake.

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.

Yote haya yanafanywa na kusimamiwa na Idara ya Vita. Jina lake linahusishwa na vita na mapigano. Vita vinahitaji jeshi, na jeshi linahitaji maandalizi na muundo, ikiwa ni pamoja na makamanda wa makao makuu, maafisa na askari.

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.

Jeshi lina bendera zake na mabango yake. Kuundwa kwake kunahitaji mafunzo, ya kimwili na ya kiufundi, ambayo yanajumuisha mafunzo ya mbinu za mapigano kwa kutumia silaha mbalimbali, kulingana na maendeleo ya kisasa ya teknolojia. Kwa hiyo, ni lazima kwa jeshi kufanya utafiti wa kijeshi na kiufundi, na kupata mafunzo ya mbinu za mapigano, pamoja na matumizi ya silaha zote za kisasa za aina mbalimbali.

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.

Kwa kuwa jeshi ni jeshi la Kiislamu, na kwa kuwa ni jeshi la dola ya Khilafah ambalo hubeba da'wa ya Kiislamu hadi ulimwenguni, ni lazima kwa vikosi vya jeshi kupata utamaduni wa Kiislamu kwa ujumla, na utamaduni mahususi wa Kiislamu unaohusiana na kanuni za vita, amani, usitishaji wa mapigano, mikataba, makubaliano, pamoja na maelezo yote yanayohitajika. Kwa hiyo, vyuo vyote vya kijeshi katika ngazi mbalimbali na misheni zote za kijeshi vinakuwa chini ya mamlaka ya Idara ya Vita.

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.

Vikosi vya jeshi lazima pia vijumuishe kitengo kinachohusika na usalama wa ndani, yaani polisi. Vikosi vya jeshi na polisi vinapaswa vyote viwe na silaha, vifaa, vifaa vya kujikimu na mahitaji yote muhimu wanayohitaji ili kutekeleza wajibu wao. Ndiyo maana kazi hizi zote zinaangukia chini ya Idara ya Vita.

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.
