Black magic is condemned in Islam but Muslim thinkers are not clear on how to deal with this superstitious holdover from an earlier age. Sorcery or witchcraft (sihr) is often equated with trickery aimed at conflating falsehood with the rational association of causes and effects. Sorcery is difficult to define. Our knowledge of sihr and what is not within reach of our sense perception is also limited. The available information in the scriptural sources of Islam also falls short of elaboration on detail. Sihr may aim at inflicting harm on its object or at realising a benefit, and the sorcerer often resorts to irrational and impermissible means. Muslim scholars have differed on the reality of sihr.
