the prophet divided the world in two contending spheres--darul-Islam(the zone of peace where the mulsims were the dominant element) and darul-Harb (the zone of war where the kafirs or non-muslims held sway). I am referring to the prophet's declaration that Allah has made him the Model of Practice for his followers. It has come to mean that the Muslims must copy him in everything, they must eat, drink, walk and talk like him, even must look like him, that is, they grow beard like his, have a similar hair-cut and dress like him. This is what is called followings the Sunnah .i.e., the Prophetic: Model which is the guarantee of salvation. One can easily say that Islam has been designed to induce respect and love for Arabia. There are express commands of the Prophet, which state that a person is not Muslim until he loves him more than his own father and mother. The idea is that people must be weaned from their own nationalities and motherlands, and attached firmly to Mecca. This is the reason that the Muslims of India call their own homeland as the battlefield and Arabia the fountain of peace and celestial glory. Now, it is perhaps, easy for you to understand why the Muslims of India partitioned their own motherland for practicing the Arab cultural values in Pakistan (and Bangladesh)
