As the influence of muftis in the courtroom has declined in modern times, there has been a relative increase in the proportion of fatwas dealing with rituals and further expansion in purely religious areas like Quranic exegesis, creed, and Sufism. Modern muftis issue fatwas on topics as diverse as insurance, sex-change operations, moon exploration and beer drinking. In the private sphere, some muftis have begun to resemble social workers, giving advice on various personal issues encountered in everyday life. The vast amount of fatwas produced in the modern world attests to the importance of Islamic authenticity to many Muslims. However, there is little research available to indicate to what extent Muslims acknowledge the authority of muftis and heed their rulings in real life.
