The Muslim Brotherhood's goal, as stated by its founder al-Banna was to drive out British colonial and other Western influences, reclaim Islam's manifest destiny—an empire, stretching from Spain to Indonesia.The Brotherhood preaches that Islam will bring social justice, the eradication of poverty, corruption and sinful behavior, and political freedom (to the extent allowed by the laws of Islam).
It downplayed doctrinal differences between schools (although takfiring Bahais and Ahmadi Muslims) emphasizing the political importance of worldwide unity of the Muslim Nation (umma).
As Islamic Modernist beliefs were co-opted by secularist rulers and official `ulama, the Brotherhood has become traditionalist and conservative, "being the only available outlet for those whose religious and cultural sensibilities had been outraged by the impact of Westernization".
Al-Banna was populist in his message of protecting workers against the tyranny of foreign and monopolist companies.
It founded social institutions such as hospitals, pharmacies, schools, etc.
According to al-Banna, contemporary Islam had lost its social dominance, because most Muslims had been corrupted by Western influences.
