Land that previously formed the bedrock upon which the Khilafah was established is called Muslim land. It is one land, as mentioned in the introduction, and is considered as such by the Khilafah. So when the Khilafah is re-established in any part of Muslim Land its outlook upon the rest of the Muslim Lands would be with a view to reunite it under Allah’s deen, Islam. Allah (swt) says,.

"Ku riƙe da igiyar Allah ku duka, kada ku rabu." [TMQ 3:103].

“Hold fast all of you to the rope of Allah and be not divided.” [TMQ 3:103].
