Studying the power-law scaling of financial time series is a promising area of econophysics, which has often contributed to the understanding of the intricate features of the global markets. In this article, we examine the multifractality of some financial processes and the underlying formation mechanisms in the context of Islamic equity markets. The well-known Multifractal Detrended Fluctuation Analysis (MF-DFA) is used to investigate the self-similar properties of two Dow Jones Islamic Markets Indexes (DJIM). The results prove that both indexes exhibit multifractal properties. By discussing the sources of the multifractality, we find that it is related to the occurrence of extreme values, the long-range dependency of autocorrelations and the fat-tailed distribution of the returns. These results have several important implications for analysts and decision makers in modelling the dynamics of Islamic markets, thus recommending efficient asset allocation plans to investors dealing with Islamic equity markets.
