Multifractal modeling has been the subject of several studies in several fields such as geophysics, climatology, image processing and the study of internet traffic. Recently, finance has been the target area for the application of fractals. Several articles have attempted to study the multi-fractality of financial series. Our paper aims to put multifractal analysis into practice in the field of Islamic finance. We have proven that Islamic stock indexes exhibit multifractality through the property of scale invariance.
