There is not doubt about existence of black magic and Jins and there impact on person (scientifically proven or not).
I was exposed to all side of this, first patient (went in for my father sake when he was at his death bad), then become disciple of a Roohani Aamil (treating peoples suffering from Black Magic/ Jins and even some medical condition using power of Quranic Ayats) , and practitioner for while before giving it up.
I have seen lives destroyed even people killed by this, (although as Muslim it is my faith that though black magic might be contributing cause but no one could die before time set by Allah).
Being outsider with some inside knowledge I can safely say that finding the right person to treat this is not an easy task, most of peoples doing this are from lower echelon of society thus easily get into greed of making money and sex (most of peoples visits them are ladies vulnerable and desperate for their matters).
I have seen so many of my ex colleagues went bad (in fact I am one of very few left honorably) my teacher was disappointed with my decision but I have no regret. I erased everything learnt, burned the note book where I kept all Tawiz, infect even forget how the write one (there is process of writing each Tawiz).
Although I do **Not **know any back magic practitioner, but after leaving my teacher, I become friends with some other Rooahi Aamil as well.
There are 3 types of Aamils.
- Those doing purely for Allah sake. There were very few and my teacher (passed aware recently) comes in this category.
- Those claims doing this purely for sake of Allah but find indirect ways to extract money and other favors)
- Those are purely commercial interests (I would not trust those advertise in anyway).
I always prefer to deal with 1 and 2, but dealing with 2 need careful handling. But on other side there are some problem with type one as well (inflated ego, expectation of one to obey and respect like a slave).
On ability to deliver, I would say dealing with Black Magic or Jin is fairly simple matter (there could be tough time if jin it too strong or difficult but nevertheless do able).
Come to solving relationship issues, if its due to black magic or Jin, (there is huge numbers of problems specially with females are due to Jin’s influence), it is fairly possible.
Even that also would need personal efforts to rebuild the damage, which sometime irrevocable then.
Other relationship issues due to personality difference, it is difficult task for any Aamil although some Dua’s / Tawiz’s and reciting some Allah’s name could help to the certain extent.
There is always possible to the one suffering from genuine medical condition (not a black magic or jin), a good Amil would immediately able to identify and advice person to seek medical help.
