She is possessed and the jinni speaks on her lips and refuses to leave her
Question

                My cousin (daughter of maternal aunt) is possessed by a jinni who speaks on her lips with a man’s voice and says that he will never leave her because he loves her. We have taken her for ruqyah many times and every time he speaks and says that he will never leave her. What should she do?.
Praise be to Allah.
    Firstly: 

    We ask Allaah to take away from your cousin what she is 
    experiencing and to heal her, and divert that jinni away from her, for He is 
    All Hearing and Ever Responsive. 

    Secondly: 

    The remedy in this case and others is ruqyah as prescribed in 
    sharee’ah, which may be done by the sick person himself or by one who is 
    treating him, and it will be beneficial by Allaah’s leave. But it may need 
    to be repeated and you may need to do other things to help it. We will 
    mention the most important of these things here: 

    1 – Reminding the sick person to always recite the adhkaar 
    for morning and evening, when going to sleep, eating, drinking, entering and 
    leaving the house, and to say a lot of dhikr in general. The best of dhikr 
    is reciting Qur’aan and the most important passages to recite are the 
    Mu’awwidhaat (soorahs seeking refuge with Allaah), al-Faatihah, Soorat 
    al-Baqarah and Aayat al-Kursiy. The more the sick person perseveres in 
    dhikr, the more the shaytaan’s influence on him will weaken, and he may be 
    expelled by means of ruqyah. 

    2 – The ruqyah should be done by a righteous person who 
    adheres to the Sunnah and who shuns bid’ah, humbug and witchcraft. 

    3 – The sick person should turn to Allaah a great deal and 
    ask Him for help, for Allaah answers the prayer of the one who is in 
    difficulty and relieves his distress, as He says (interpretation of the 
    meaning): “Is not He (better than your gods) Who responds to the 
    distressed one, when he calls on Him, and Who removes the evil, and makes 
    you inheritors of the earth, generations after generations? Is there any 
    ilaah (god) with Allaah? Little is that you remember!” [al-Naml 27:62]. 
    Especially if the du’aa’ is offered at times when a response is more likely, 
    such as between the adhaan and iqaamah, just before dawn, in the last hour 
    after ‘Asr on Friday, when breaking the fast, and when travelling. 

    4 – Always offering the five daily prayers on time. 

    5 – Repenting to Allaah from sins that may be the cause of 
    the shaytaan gaining control of a person. 

    6 – Purifying the house of things that the shaytaan loves, 
    such as images, dogs, music and singing. Imagine this devil being cornered and 
    having no food or drink or pleasure. He may be deprived of that by saying 
    the name of Allaah over food and drink and by getting rid of things that he 
    loves. Would he want to stay?
