Should they obey the woman who treats people with ruqyah?

My mother used to take a woman who recites Quraan to my grandmother's
home so that she recites on our grandmother. As my grandmother is old,
disabled, and reached the stage of senility although she is not very
old. This woman recites Quraan on my grandmother and sometimes on my
mother. One time while she was reciting she held my mother's head so
my mother started screaming. I did not see this but my mother told me.
Now my mother goes regularly to this woman and she takes my sister and
me with her. When she recites onmy mother, my mother raises her hands
like if she wants to hit someone, her nails comeout and she starts
sayingthreatening statements and slanders the Quraan.
This woman told us that she is possessed by a devil, and that our
mother is under spell. She also told us that the devil wants her to
become disabled like mygrandmother and lose her mind as well. She
advised us to read surat al-baqarah everyday andto recite Quraan
always at home. She also gave us olive oil, jujube, honey, black seeds
and pressed dates, and advised us to use them always. She also advised
us to spread water with salt and rose water at home alternatively on
daily basis.
The question:
Is it permissible for us to use those things she gave us? Is what we
do considered shirk?.
Praise be to Allaah.
We ask Allaah to grant your mother quick and full healing by His Leave
and to decree for her and you reward, patience and steadfastness.
We do not see anything in your question that would make us say that
you should not go to that woman who treats people with ruqyah. It says
in the question that she does ruqyah by reciting Qur'aan, and sheuses
blessed oil (i.e., olive oil) and 'ajwah dates which protect against
poison and spellsby Allaah's Leave, and the fragrance of rose water
which gives one strength to resist witchcraft and hasad (destructive
envy); some of them also use 'ood (aloeswood) and bukhoor (incense) to
achieve the same purpose. All of these are things that are acceptable
in sharee'ah in sha Allaah.
But what we see here is the use of salt which is sprinkled in the
house, and we are afraid that this idea may have been picked up by
some of those who do ruqyah from the myth or belief of the common folk
that salt wards off the evil eye and so on.
We asked some of those who do ruqyah about that and he said that
salthas no such effect, even though some people useit.
What we advise you to do is to be fully aware ofwhat words and
recitations she uses in her ruqyah, and if she uses anything other
thanthe Islamically acceptable words such as dhikrs, du'aa's and
verses, such as things that cannot be understood, or you haveany
doubts about her, then hasten to ask her about what it means, and ask
knowledgeable people about her. Many of those who treat people with
ruqyah pretend to be reciting Qur'aan to fool the listeners, when in
fact they are using sihr (witchcraft) and trickery and using hidden
words which they say or write in order to harm the sickperson so that
he will carry on coming to him and giving him money.
