Going to the church and seeking help from the priest
Question

                It was suggested to me that I should go to the church and tell the priest that I am suffering from problems connected to witchcraft. Please note that I have gone to many shaykhs.
Praise be to Allah.
    It should be noted that ruqyah is one of the types of remedy 
    prescribed in Islam, but there are certain conditions for it to be 
    beneficial and acceptable, just as physical medicine has conditions for it 
    to be suitable. 

    Al-Haafiz Ibn Hajar (may Allah have mercy on him) said: 

    The scholars are unanimously agreed that it is permissible to 
    use ruqyah if three conditions are met: it should based on the words of 
    Allah, may He be glorified and exalted, or His names or His attributes; it 
    should be in Arabic or in words the meaning of which can be understood; and 
    it should be accepted that ruqyah does not have any effect in and of itself, 
    rather that happens by the will and decree of Allah. 

    End quote from Fath al-Baari. 

    The scholars have stipulated that the ruqyah should be in 
    Arabic or in words that are known and understood, lest the words of the one 
    who does it constitute shirk or could lead to shirk, without the one for 
    whom it is done realising that. This problem is more serious if the one who 
    is performing ruqyah is one of the People of the Book, who are people of 
    shirk. It is to be expected that they will perform ruqyah by saying things 
    that are in accordance with their religion, especially if they do so in a 
    language that the one for whom it is done does not know, and especially if 
    the one who is seeking the ruqyah has gone to them in their churches or 
    monasteries. 

    This is the reason why some of the scholars did not allow 
    People of the Book to perform ruqyah for Muslims. 

    Ibn ‘Abd al-Barr (may Allah have mercy on him) said: 

    Maalik did nor approve of ruqyah done by the People of the 
    Book. That was because – and Allah knows best – it cannot be known whether 
    they will recite from the Book of Allah, may He be exalted, or use words 
    that constitute witchcraft. 

    End quote from al-Istidhkaar, 9/376 

    For that reason, those scholars who allowed the ruqyah of the 
    People of the Book stipulated that the ruqyah should be done using words 
    that are known to be the words of Allah or dhikr. 

    See al-Umm by al-Shaafa‘i, 7/228 

    There is no doubt that to be on the safe side with regard to 
    one’s religious commitment and to avoid falling into error, one should keep 
    away completely from asking the People of the Book for ruqyah, especially 
    since their insincerity towards the Muslims is well known. Indeed it is also 
    well known that they either seek the help of the jinn and shayaateen in what 
    they do, which means that their ruqyah comes under the heading of 
    witchcraft, or they bring the cross close to the one who is sick and seek 
    the help of their brethren of the shayaateen by doing so, according to what 
    is mentioned above of the words of Ibn al-Teen (may Allah have mercy on 
    him). 

    The issue of ruqyah is easy, in sha Allah and there are many 
    righteous Muslims who are able to do it well. There is nothing more 
    beneficial than a person performing ruqyah for himself, reciting the words 
    of Allah or du‘aa’s that are soundly narrated from the Prophet (blessings 
    and peace of Allah be upon him). 

    Hence the scholars of the Standing Committee issued a fatwa 
    stating that that (going to a Christian priest) is not permissible, when 
    they were asked: 

    The remedy for seizures among us in Egypt is to go to the 
    church, especially the church of Mary Jarjis, or to go to practitioners of 
    witchcraft and charlatans who are widespread in the villages. Sometimes that 
    brings results. Is it permissible to do that? Please note that if the person 
    who has a seizure is not treated quickly, he will die. 

    What is the remedy prescribed by Allah for this sickness, as 
    there is a remedy for every disease except old age? 

    The scholars of the committee replied: 

    It is not permissible to go to the church to treat seizures, 
    or to go to the practitioners of witchcraft or the charlatans. As for 
    permissible remedies, he may be treated by means of ruqyahs that are 
    acceptable in Islam, such as reciting Qur’aan, e.g., al-Faatihah, Qul 
    Huwa Allahu Ahad (Soorat al-Ikhlaas), al-Mu‘wadhatayn (the last 
    two soorahs of the Qur’aan in which refuge with Allah is sought) and Aayat 
    al-Kursiy, as well as dhikrs and du‘aa’s that are soundly narrated from the 
    Messenger (blessings and peace of Allah be upon him). And Allah is the 
    source of strength. End quote.
