Black Magic (Jaadoo) and Jinn

Q: I have a question about fairies... Should we have faith in them... What if they offer you some money and should we talk to them if they want to talk to us?

Q: My sister has come to know that black magic is being used to disturb and destroy her house. Her husband beats her everyday, threatens her that he’ll divorce her. He is also involved in extramarital affairs. This has been going on for the last 2 years. My sister reads Surah Baqara daily, offers 5 times prayers, and sincerely prays to Allah for relief but she has been in severe pain due to her husband’s attitude towards her. Recently she has come to know that somebody in her family is using black magic against her to destroy her relationship with her husband.

Somebody referred my sister to a guy who can destroy the black magic by using black magic. He claims that she’ll live a happy life with her husband once he is done with his magic. My sister has given him money to use black magic knowledge to destroy the black magic which is being done on her. Now my questions are:

1. What is the Shariah ruling on somebody using black magic to stop black magic?

2. Has my sister committed kufr?

3. Has my sister committed shirk?

4. If she has committed shirk by this way, is there anyway she could be forgiven by Allah?

5. Can she still go to heaven? She has been a pious woman all her life before this.

Q:

1. Does black magic cause cancer?

2. Can we know who did black magic on us? 

Q: Is it right to fear jinns because I always see people get very scared about them and wear 'taweez' (surahs written on folded paper), especially in the Indian subcontinent. But the jinns are not as supreme creatures as humans. Though I believe in them, I never fear them, actually I don't care about them. Am I doing right?

Q: If two humans are talking to each other and the third person is a jinn who is listening to their talk, what dua should be recited so that the jinn does not listen to our talk?

Q:

1. It has been confirmed from three authentic sources that my husband has sihr. As part of his treatment I must read Surah Baqarah daily for 40 days. Sometimes I play it on my laptop on days that I can't read. Is it jaiz (acceptable) to play in the house, office when no one is there on the same floor for protection? I heard that recitation of Surah Baqarah protects any home for 3 days from bad influences.

2. My husband naturally is resistant to treatment despite being incredibly religious himself. All the signs are there between us, his business, consistent thefts by employees and him not taking action. Is there anything else I can do apart from Surah Baqarah and Ruqyah Shariah?

3. My husbands shaikh insists that there is no such thing as sihr (though it was done on the Prophet) and doesn't advise seeking treatment because he believes no human being has such power over another, its impossible. He never advocates treatment. Isnt it haraam to consistently prevent someone from seeking treatment, also to openly disregard that sihr doesnt exist in todays day and age?

4. What is the reality regarding sihr and its effects, and what is correct treatment for sihr?

Q: I am a 22 year old male. 2 years I was in love with a girl and then we broke up. I was deeply in love with her so my freind suggested that I go to a magician (peer) so I went to a Shia magician and he told me to do these things:

1. Put sand outside the house of the one I love

2. Put one date (kajoor) inside mud

3. Put your photographs inside honey

4. Put one big stone on a taweez

5. And he gave me one human like page and told me to put it inside some graveyard and put a thread in its throat.

I have done all these things  but after 1 month I felt that I am doing sihr so I decided stop. I called the magician and told him that I dont want her anymore. He told me to drop all the things in water. I dropped the honey in water, the taweez in water, but the date (kajoor) is still inside the mud and the page is inside the graveyard. My mission was not completed and the girl didnt come back. There was no harm caused to that girl. So now I want to repent. 

1. Do I have to remove the date (kajoor) from the mud?

2. Do I have to remove the page from the graveyard? I remember the graveyard but I don't remember the exact place where i put it.

3. How do I repent and what do I do?

Q: I want to know about black magic. Is it permissible to practise it for a good purpose?

Q: Is there any evidence that Jinn are attracted to perfume, women and an unclean person and when someone goes out at night? 

Q: Do jins do hifz?
