the caliph owns the so called caliphate.

from wiki:

The Caliph (Arabic: خليفة‎; /khalīfah) is the head of state in a Caliphate, and the title for the leader of the Islamic Ummah, an Islamic community ruled by the Shari'ah. It is a transcribed version of the Arabic word Khalīfah which means "successor" or "representative".

The term caliphate (from the Arabic خلافة or khilāfa) refers to the first system of government established in Islam, and represented the political unity of the Muslim Ummah (nation). In theory, it is a constitutional republic, meaning that the head of state (the Caliph) and other officials are representatives of the people and must govern according to Islamic law, which limits the government's power over citizens.
