The ruling system is built upon four principles which are:

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

Authority is for the people.

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

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.
