We have a duty to Allah to live by Islam which means under the State
We have a duty to Allah to live as one ummah under one leader,
we must re-unify and join the Khilafah "Caliphate"
We have a duty to Allah to carry Islam to the rest of the world,
to ensure the non Muslims also live by the justice of the Islamic system
