Sudanese Islamic renewal movement formed in the 1960s. Led by Mahmud Muhammad Taha. Defined religion as a behavioral system of morals employed to attain peace, genuine freedom, and ever-growing, eternal happiness. Advocated federal democracy with economic socialism and equal political rights for all, regardless of gender or religion. Opposed implementation of traditional Islamic legal codes since they reflect fundamental political, economic, and social inequalities. Promoted use of ijtihad in reinterpreting and implementing Meccan, rather than Medinan, verses of the Quran. Had a small membership but was well known internationally. Dormant as an organization since Taha's execution in 1985.
