Besides political parties, various Islamist organisations have played important roles in shaping the discourses and practices of political Islam in Malaysia. While these organisations share conservative views on numerous religious, moral and gender issues, they have different approaches when dealing with topics such as nation-building, multiculturalism, democracy and attitudes towards non-Muslims. Some have been more moderate and inclusive in their outlooks, while others have chosen a more hardline and exclusivist position. These two diverging practices of Islamism coexist, compete, and often co-constitute each other. How do we understand and capture such Islamist competition and transformation in Malaysia and elsewhere? Based on participant observation, online documentation, and interviews, this chapter explores such contestations by examining the discourses and activities of two major Islamist organisations—IKRAM (the Malaysian IKRAM Association) and ISMA (Malaysian Muslim Solidarity Front). Moving beyond the debate of post-Islamism and Islamism, this paper suggests describing such contestation as a competition between moderate, multicultural Islamism and extreme, right-wing Islamism.
