Hasan Al-Turabi

"Turabi’s concepts of an Islamic state have aroused significant criticism, not because of  his concepts but rather, because of his practices as a political activist working with military dictators. When he described the nature of an Islamic State, he argued that such a state could take different forms, depending on the specific conditions of particular time and place. However, in accord with the principle of tawhid, the state would not be secular – separating religion from public life. In whatever form the Islamic state took, it would emphasize justice and avoid oppression. The criticism of Turabi comes from the fact that, in practice, he supported oppressive military dictatorships that claimed to be implementing Shariʻa."
