I would appreciate if the author duly acknowledges the source of
the video from which it was uploaded.
The woman in the video was possessed by a Jinn. For those who does
not know, in Islam, unlike Satan and Angels, Jinns are divided into
Muslims and non-Muslims, much like us humans. So back to the
story...
The Imam was the one who conducted the 'exorcism'. Apart from
exorcising the Jinn, the Imam also in the end converted the Jinn
into a Muslim. The name of the Jinn is Idrus and was made into a
promise never to disturb humans after the exorcism.
