Note the Quote

“It is one of the greatest frauds on the people to suggest that religious affinity can unite areas which are geographically, economically, linguistically and culturally different. It is true that Islam sought to establish a society which transcends racial, linguistic, economic and political frontiers. History has however proved that after the first few decades or at the most after the first century, Islam was not able to unite all the Muslim countries on the basis of Islam alone.”
