This chapter concerns a 2005 Malaysian court case in which the plaintiff defaulted on home-purchasing loan and then claimed he could obtain favourable repayment terms if he switched his borrower from Affin (Islamic) Bank to a regular commercial bank. According to the local regulatory framework, all commercial transactions, including those of Islamic banks, fall under the jurisdiction of the civil courts. The government issued a specific law - namely the Islamic Banking Act 1983, later enhanced as the Islamic Financial Services Act 2013 - to regulate the Islamic banking and financial industry. As Malaysia practises a dual banking system, whereby Islamic banking products are offered side by side with the conventional ones, the case presents interesting comparison between the two banking products.

In Sudan the era of the oil boom resulted in a flood in labor remittances that circumvented official financial institutions, thereby undercutting the state’s fiscal and regulatory capacity and fueling the expansion of the informal foreign currency trade. Initially, developments in Sudan paralleled those in Egypt as the boom witnessed the rise of an Islamist-commercial class that formed as a result of its successful monopolization of informal financial markets. However, in contrast to Egypt, by 1989 Sudanese Islamists were able to take over the levers of the state via a military-coup. This development was made possible by Sudan’s weaker state capacity and the extreme weakness of its formal banking system. As a result, the financial power of the Muslim Brotherhood continued to increase in relationship to the state as they continued to profit from participation in the lucrative speculation in black market transactions and advantageous access to import licenses.

Observable implications ofthree existing theories of the Islamic advantage -- grievances, faith, information -- are tested using a variety of data sources. Contrary to the expectations of grievance theory, individuals in the Muslim world appear to be more dissatisfied and less apathetic. Moreover, participation rates are lowest among the most aggrieved, much as they are elsewhere in the world. In contrast to what the faith-based theory expects, participation rates are significantly lower among individuals with the strongest religious beliefs. Further, the popularity of Islamic-based political and economic movements does not appear to follow trends in religiosity in the aggregate, neither across space nor across time. Instead, support for these movements appears to come from both the religious and the secular, in Turkey and across the Muslim world. Finally, there is little evidence that voters in Muslim countries are uninformed, generally, or better informed about Islamic-based parties, in particular. The lack of support for the all three existing theories reopens the puzzle of Islamic-based movements yet again.
