Tsarin mulki yana dogara ne a kan ka'idoji guda hudu, wadanda sune:

The ruling system is built upon four principles which are:

Mulkin ƙasa na Shari'a ne, ba na al'umma ba.

- Sovereignty is for the Shar’a, not for the Ummah.

Iko ya kasance ga jama'a.

Authority is for the people.

Nada wani Khalifa guda ɗaya abu ne wajibi ga dukkan Musulmai.

The appointment of one Khaleefah is an obligation upon all the Muslims.

Karɓar dokokin Allah ita ce keɓantaccen haƙƙin Khalifa, don haka shi ne yake kafa kundin tsarin mulki da dokoki iri-iri. Waɗannan su ne ginshiƙan mulki a Musulunci, waɗanda ba tare da su ba mulki ba zai wanzu ba. Idan wani daga cikin waɗannan ginshiƙai ya ɓace, to mulkin zai ɓace, wato mulkin Musulunci, wato ikon Musulunci, ba kowane irin mulki ba. Waɗannan ginshiƙai an samo su ne daga Shari'a, kuma hujjoji daga Shari'ar sun tabbatar da su.

The adoption of the divine rules is the exclusive right of the Khaleefah, so he is the one who enacts the constitution and the various cannons These are the principles of ruling in Islam without which ruling can’t exist. If any of these principles was absent then the ruling will vanish, meaning the Islamic ruling, i.e. the authority of Islam and not any ruling. These principles have been derived and backed by evidences from the Shari’ah.
