Tashqi ishlar bo‘limi Xilofat davlatining xorijiy davlatlar bilan munosabatlariga oid barcha tashqi ishlarning, ular qanday bo‘lishidan qat’i nazar, mas’uliyatini o‘z zimmasiga oladi. Bu ishlar siyosiy jihat va unga tegishli masalalarga, jumladan, ittifoqlar tuzish, tinchlik shartnomalari, o‘t ochishni to‘xtatish bitimlari, muzokaralar, elchilarni tayinlash, elchi va vakillar yuborish hamda elchixonalar va konsulliklar ochishga taalluqli bo‘lsa ham shunday. Shuningdek, iqtisodiy, qishloq xo‘jaligi va savdo masalalari, shuningdek pochta aloqasi yoki simli va simsiz aloqa va boshqalarga oid munosabatlarni ham o‘z ichiga oladi. Tashqi ishlar bo‘limi bu barcha masalalarni boshqaradi, chunki ular Xilofat davlatining boshqa davlatlar bilan munosabatlariga taalluqlidir.

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.

Rasulullah ﷺ tashqi davlatlar va boshqa tashkilotlar bilan siyosiy munosabatlar o‘rnatgan. U zot ‘Usmon ibn ‘Affonni Quraysh bilan muzokara olib borish uchun yuborgan, xuddi o‘zlari Quraysh vakillari bilan muzokara qilganlaridek. U zot podshohlarga elchilar yuborgan va podshohlar hamda yetakchilarning elchilarini qabul qilgan. Shuningdek, u zot ahdnomalar va tinchlik shartnomalari tuzgan. Xuddi shunday, u zotdan keyin uning xalifalari ham boshqa davlatlar va tashkilotlar bilan siyosiy munosabatlar o‘rnatib kelganlar. Ular bu ishlarni o‘zlari nomidan bajarish uchun odamlarni tayinlar edilar, chunki inson o‘zi bajara oladigan har qanday ishni boshqa bir kishiga o‘z nomidan bajarishni topshirishi mumkin, degan asosga tayanib.

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.
