The Prophet صلى الله عليه وسلم said: “This matter (Khilafah) will continue after me in Al-Madina, then (move to) Al-Shaam, then to the peninsula, then to Iraq, then to the city (Constantinople), then to Bait-ul-Maqdis. So if it reaches Bait-ul-Maqdis, then it would have reached its (natural resting place); and no people who remove it (i.e. the capital of the Khilafah) from their land will ever get it back again (for them to be the capital again).”
