It has been mentioned before that one of the tasks of the executive assistant is to be an intermediary between the Khalifah and the states concerning the international relations. .

The Messenger (PBUH) and the khulafa’ rashidun used to address these relations directly through their secretary, i.e. the executive assistant. .

The Messenger (PBUH) is the one that carried the correspondence regarding the Hudaybiyah treaty and concluding the peace agreement. It was also reported from ‘Umar (ra) that when the delegate from Kisra came to him he found him sleeping at one of the gates of al-Madin al-Munawwarah. .

However, the Khalifah is allowed to address the international relations directly through his executive assistant as well as through appointing a manager in charge of international relations, the same as any other organisation in the State. .

Therefore, these four departments can be assembled under one department, called the department of the amir of jihad, because their subject is linked together. They can also be separate from one another as dealt by the Messenger (PBUH), as mentioned before. .

The work these four departments cover is vast, particularly as witnessed today where there are numerous fields. These include those of the armies, internal problems, and art of intrigues devised by the states, agents, classes of the mercenary politicians, various crimes, and complications in the international relations. In addition to this, there are various fields of industry and advanced technical means in use. Hence, in order that the mandatory powers of the amir of jihad do not expand, which may lead to him holding the centre of the State’s power that might cause harm to the State if his taqwa declined; Due to all these points we adopt keeping these departments separate from each other, and linked to the Khalifah as departments independent from the State’s organisations, as follows:.

• Amir of jihad- war department (army) .

• Department of internal security .

• Department of industry .

• Foreign department.
