No, its a little complicated bro..
First of all, taking any kind of help from any kind of Jinn is not permitted..
They are good jinns.. but.. there is more to the story
Those who have knowledge about this subject say that Muwakkils are jinns, who think themselves as self appointed guardians of Quran.. They consider themselves as Angels (lolz).. and whoever has contact with them, they tell him that they are angels.. in fact they are jinns..
Each one of them continuously recite different Surah of Quran.. They think that reciting the Surah means protecting the words.. (well it is true in a sense because Hafizeen are also protectors in a way). So whoever recites the Surah continuously, they become friends with them.. Then they talk to them and tell the humans to ask them what they want.. Mostly people do wazifa of certain Surah to achieve this objective.. Once they become friends, these humans ask them for a lot of help.. including killing the jinns which are sent by Magicians..
But overtime, these jinn become possessive about the relationship.. So if a person stops some good acts, they force him to do it.. For example, if a person decides to go to a night club, they create such circumstances which are sometimes too dangerous.. If a person doesn't go to mosque for prayers, they force him to go.. and that's why the life becomes very difficult..
They are self appointed extremist jinns..
And getting any kind of help from them is not recommended..
Good!
