Fathwa, - Her daughter's future in-laws seek help from Awliaa' and visit their shrines

Question
Assalamu walikum I Need help and advice on wat to do for my daugher
who's marriage is being fixes at the moment, I have just found out
that the family she will be marring into have a different Muslim
belief then us they believe in phir awalia and do every thing
according to that, they have shrines that they visit )azmi sharif( for
example and also shrines of other Awalias who are their descendants.
We are Sunni Muslims and only believe in our beloved prophet Mohammad
)pbuh( they believe that these descendants advice them about every
thing in life as we do Istakara. I am shocked and heart broken by
hearing this as the children that will be born will have to follow
that belief. Am I being stupid to think this isn't right. My daughter
is heart broken too, wat do I do? To me they sound like Shia Muslim
not that I have any thing against Shia Muslim, as a Sunni I have a
very big doubt in my mind I asked the parents if they were Shia they
denied it, so wat kind of Muslim are they? Can any one tell me wat
this belief is. I'm worried and scared of the shame in the family that
I will have to go through if I break this alliance. Or am I being too
skeptical about their beliefs pls some one help me to understand this
kind belief . I thank u all as a heart broken mother
Answer
All perfect praise be to Allaah, The Lord of the Worlds. I testify
that there is none worthy of worship except Allaah, and that Muhammad,
is His Slave and Messenger.
If the groom and his family believe that the dead have control over
the universe, know the unseen, remove distresses )from people( and the
like of what is exclusively related to Allaah The Almighty only, or
they direct an act of worship such as supplication, slaughtering and
the like to the dead people, then this is all included in the major
form of Shirk that takes one out of the fold of Islam and it is not
permissible to give your daughter in marriage to the one who holds
that belief and does such polytheistic matters. For more benefit,
please refer to Fataawa 82393and 85126.
Accordingly, it is not permissible to let fear of shame prevent you
from canceling that engagement. This has nothing to do with
exaggeration or stupidity. Rather, this is something Islamically
obligatory upon you. It is not important to know the name of the sect
that they belong to; rather, what is important is to know the reality
of their beliefs and acts because they are the main principles on
which the ruling of marrying them is based.
As for your statement "we are Sunni Muslims and only believe in our
beloved ProphetMuhammad", we do not know what you mean by that. Sunni
Muslims believe thatMuhammad, is the slave and messenger of Allaah and
do not believe that the Prophet, has something from the
characteristics of Allaah, as Allaah The Almighty says )what means(:
• }Say, "I hold not for myself ]the power of[ benefit or harm, except
what Allaah has willed. And if I knew the unseen, I could have
acquired much wealth, and no harm would have touched me. I am not
except a warner and a bringer of good tidings to a people who
believe."{]Quran 7:188[
• }Say, "I am only a man like you, to whom has been revealed that your
god is one God. So whoever would hope for the meeting with his Lord -
let him do righteous work and not associate in the worship of his Lord
anyone."{]Quran 18:110[, among many more other evidences.
Allaah Knows best.
