Is It Haram  to Talk to Jinn?
Question

I spoke with this guy who´s known to have some powers to talk with Jinn, I guess the Muslim ones, and he told me some stuff about me.  Those people use words and phrases from the Quran to control Jinn. 
What do you think about those people ? And is it OK to speak with them? And who are  Ahl al-Kitab? 
Frankly, I read books, they mention how to make ( TAWEEZ), and how to control Jinn, and see angles, and these books use Quran´s words. I would like to know more about this.
Praise be to Allah.Is it possible to talk to the jinn?
It is possible to talk to the jinn , but finding out about unseen matters and what is in people’s hearts is haram. Usually those who use words and phrases of the Quran in order to gain control over the jinn use ways that are not Islamic. 
Can you use the jinn?
Using the jinn is a power that was given only to Sulayman (peace be upon him). Hence when the Prophet (peace and blessings of Allah be upon him) wanted to tie up a jinni whom he had overcome during his prayer, he remembered the du’a of Sulayman and did not do that.
So you should try to advise these people and if they respond, all well and good; otherwise the safest thing to do is to leave them alone and not speak to them.
Who are Ahl al-Kitab?
Ahl al-Kitab (the People of the Book) are the Jews and Christians.
Is it haram to talk to the jinn?
It is OK to speak with the jinn if this happens without you seeking it, and in fact it is mustahabb to call them to the religion of Allah and to adhere to His Shari`ah, just as you call people. It is not advisable to read books or to recite Quran for this purpose, because the Quran was not revealed for such things; it was revealed to be a light and a guide in the life of the Muslim, so that the Muslim can follow it, obeying its commandments and avoiding that which it forbids.
Can you see the angels?
With regard to the angels , the Prophet (peace and blessings of Allah be upon him) and other prophets saw them, and some of the awliya (close friends of Allah) spoke with them. `Imran ibn Husayn (may Allah be pleased with him) said that the angels used to greet him with salam until he started to use branding (cauterization for medical purposes), then they stopped. When he stopped using branding, they started to greet him again. 
And Allah knows best.
