As salamu allaiqum,
If a person has been possessed by a jinn and faces certain problems due to this, then in such a case he may head out straight for some amil. But sometimes it so happens that the jinn cunningly leaved the body of the victim ,when he consults an amil. So the amil denies the presence of any jinn in the victim’s body. Then the victim takes the second route and starts visiting doctors ,ending up wasting his time ,money and energy. So in such situations when jinns hide themselves and don’t come out in front of amils ,I am telling you the procedure of dealing with such jinns. This amal is meant only for the muslims.
Read Durud shareef (any one)11 times, then Surah Naas 11 times and then 11 times durud shareef again after every namaz. Inshallah the jinns will be compelled to leave the victim. Since these evil powers have a tendency to return again ana gain, so it is advisable to continue the amal even after the problem gets cured for say a period of six months, then see whether you are facing any symptom of being possessed by jinns. If not then you may discontinue the amal. This amal is totally safe. If the jinn does not hide, then an amil can be consulted. But if he hides in a cunning way, to avoid getting expelled by the amils, then in such a case, this amal is the best solution. If the victim reads Ayatal kursi too along with the amal, then it would yield better results.
