外交部负责处理哈里发国家与外国之间的一切外交事务,无论这些事务和关系是什么性质。无论是政治方面的事务及其所涉内容,例如缔结盟约、和平条约、停火、谈判、任命大使、派遣使者与代表,以及设立使馆和领事馆;还是与经济、农业和贸易事务有关的关系,以及邮政通信或有线、无线通信等。外交部管理所有这些事务,因为它们都关系到哈里发国家与其他国家之间的关系。

The foreign affairs department undertakes the responsibility of all foreign affairs, pertaining to the relations 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 like the formation 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 economical, agricultural, and trading matters as well as postal communications or wire and wireless communications etc. The foreign affairs department runs all these matters, because they are concerned with the relations of the Khilafah state with other states.

先知ﷺ与其他国家和实体建立了对外关系。他派遣‘Uthman bin ‘Affan前去与古莱什人谈判，正如他也与古莱什的使团进行谈判一样。他派遣使者去见各国君主，也接待君主和领袖们派来的使团。他还缔结了盟约和和平条约。同样，在他之后，他的哈里发们也与其他国家和实体建立政治关系。他们委派人员代表他们执行这些事务，依据的原则是：凡是一个人自己能够做的事，他都可以委托他人代表自己去做。

The Messenger (pbuh) established foreign relations with other states and entities. He sent ‘Uthman bin ‘Affan to negotiate with Qur’aysh just as He negotiated with the delegates of Qur’aysh. He sent delegates to Kings and He received the delegates of Kings and leaders. He also concluded pacts and peace treaties. Similarly after him, his Khulafaa’ used to establish political relations with other states and entities. They used to appoint people to carry out these actions on their behalf, on the basis that whatever an action a person can perform by himself, He can delegate it to some other person to carry out it on his behalf.
