外交部负责处理哈里发国与外国之间的一切外交事务,无论这些事务和关系属于何种性质。其中包括政治方面的事务,例如缔结条约、和平协定、停火协定、进行谈判、任命大使、派遣使节和代表,以及设立使馆和领事馆。它还包括与经济、农业和贸易相关的关系,以及邮政通信或有线、无线通信等事务。所有这些事务都由外交部负责管理,因为它们都涉及哈里发国与其他国家的关系。

The foreign affairs department undertakes the responsibility of all foreign affairs, pertaining to the relation of the Khilafah State with the foreign States, whatever these affairs and relations may be. Whether they are related to the political aspect and what it entails in the forming of pacts, peace treaties, cease-fires, negotiations, appointing ambassadors, sending messengers and delegates, and establishing embassies and consulates. It also includes relations, which are related to matters that are economical, agricultural, and are to do with trade as well as postal communications or wire and wireless communications etc. All of these matters are run by the foreign affairs department, because they are concerned with the relations of the Khilafah State with other States. .

使者(愿主赐其平安)曾与其他国家和政权建立对外关系。他派遣'Uthman b. Affan前去与古莱什人谈判,正如他与古莱什使团进行谈判一样。他派遣使者前往诸王那里,也接见诸王和埃米尔们的使者。他还缔结盟约与和平条约。同样,在他之后,他的哈里发们也与其他国家和政权建立政治关系。他们委派人员代表自己执行这些事务,其依据是:一个人能亲自做的任何事情,他都可以委托他人代其执行。

The Messenger (PBUH) used to establish foreign relations with other States and entities. He sent ‘‘Uthman b. Affan to negotiate with Quraish just as he negotiated with the delegates of Quraish. He sent delegates to the kings and he received the delegates of kings and Amirs. He also concluded pacts and peace treaties. Similarly after him, his Khulafa’ used to establish political relations with other States and entities. They used to appoint people to carry these actions out on their behalf, on the basis that whatever action a person can perform by himself, he can delegate it to some other person to carry out it on his behalf. .

由于国际生活的复杂性，以及国际政治关系的广泛性和多样性，我们采纳这样的主张：哈里发应当在国家内设立一个专门负责国际关系的机构，代表他行使职权。哈里发对该机构的管理，与对国家内其他治理和行政机构的管理一样，既可以直接进行，也可以通过执行助理进行，并须遵循相关的天经规则。

Due to the complications of international life, besides the expanse and variety of international political relations, we adopt that the Khalifah should delegate an organisation in the state specific to the international relations on his behalf, where the Khalifah pursues its work as he does with any other ruling and administrative organisation in the state, whether directly or through the executive assistant, in accordance with the related divine rules.
