Title:
Islamism

Context:
Maududi also believed that Muslim society could not be Islamic without Sharia, and Islam required the establishment of an Islamic state. This state should be a "theo-democracy," based on the principles of: tawhid (unity of God), risala (prophethood) and khilafa (caliphate). Although Maududi talked about Islamic revolution, by "revolution" he meant not the violence or populist policies of the Iranian Revolution, but the gradual changing the hearts and minds of individuals from the top of society downward through an educational process or da'wah.

Question:
What is the English translation of tawhid?

unity of God
