Can the Raqi tell if an illness is devil possession or something else?
Obviously, the experienced Raqi has examined and treated such varied cases as well as similar ones that he has become skilful at diagnosing psychological illness through his knowledge of their typical symptoms. However, not all Raqis do have such knowledge. Some Raqis may claim to have it, but in fact they do not, for they depend, when diagnosing, on mere guessing, not on proven knowledge.
