The Institutions of State in the Khilafah by Hizb ut-Tahrir

Jihad is the peak of Islam and the fundamental method defined by Islam to convey the message of Islam to the world. Conveying the Islamic da’wah is considered the main function of the Islamic State after implementing the rules of Islam internally. .

Jihad is the war undertaken for the sake of Allah (S.W.T) to raise high His (S.W.T) word. The undertaking of jihad requires an army, preparing and forming of its leaders, chiefs of staff, officers and soldiers. It also requires training programmes, supplies and ammunitions. The army also needs weapons, which needs industry. Therefore, industry is one of the necessities of the army and the necessities of jihad. This fact dictates that industry in all factories of the state must be built on the basis of the military industry. .

Moreover, the stability of the internal situation strengthens the army in fighting. However, if the internal situation is not secure and stable, then this should preoccupy the army by preparing the ground before turning to jihad. Even if the army engaged jihad, and the internal situation behind it became unsettled, then this would weaken the power of the army which would affect it in continuing its fight. .

The foreign affairs with other states are also linked to conveying the Islamic da’wah. .

Therefore, these four departments, namely the army, the internal security, the industry and the foreign affairs can constitute one department headed by an amir appointed by the Khalifah, because it is linked to jihad. .

However, it is allowed to make these departments separate from each other. Thus, the Khalifah appoints a manager for each one, and an amir to the army. The Messenger of Allah (PBUH) used to appoint leaders over the army during the expeditions without them having any relation to the industry, which the Messenger (PBUH) used to commission to others. This also applies to the internal security in terms of police, patrols and dealing with the highway robbers and thieves. This is the case regarding the foreign affairs, .

where the letters of the Messenger (PBUH) to the kings and rulers at his time give this indication. .

The disconnection between these departments through a manager for each one of them is proved by the following Articles: 8.1 Firstly: The army.

8.2 Secondly: The internal security.

8.3 Thirdly: The industry.

8.4 Fourthly: The international relations.

8.5 Fifthly: Amir of Jihad – War department (The army).

8.6 The army divisions.

8.7 The Khalifah is the army’s leader.

8.8 Sixthly: The Internal Security.

8.9 Seventhly: The Foreign Affairs.

8.10 Eighthly: The Industry.
