Am i doing wrong to my parents, am i a sinner. PLS HELP ME........

Bismillah irrehman irrahim.

As Salam Alay Kum,

I hope you will help me to live a happy life with peaceful mind.
Its in quran and hadiths, one should worship, none other than Almighty Allah or should not include any other god with Almighty Allah. its a big sin........ on other hand it has ordered that one should obey & respect their parents at any cost until and unless they are not shirk.
What should a child do, if the parents themselves are including idols with Allah and his Vali's and auliyas.
I want to be very clear with the question, and in short i'll tell whats happening with my parents

Sir. My father and his sister Raziya says that allah has sent an angel specially for them who they call Hakim Saheb & Baba Huzur, and they offer niyaz on some sweets and keep them in a closed room for some time, where only raziya stays for 10 minutes and then she also comes to other room. and after some time when all the peoples goes to that room, it seems like some one has tasted from that sweets, and raziya says that the angel and my grandfather (my fathers father spirit) has come and tasted that sweets.
And they say that the angel which is coming to them is none other than krishna (hindus god), and according to my father and raziya krishna is part of our islam, when i asked them about this angel (Krishna) they told that the angel is (naa' uzubillah) Hazrat Ali. they say that krishna is Hazrat Ali, whome god has sent for them.
I have seen the idol of krishna in my house, and also in raziyas house and photos of krishna in fathers bag and vallet.

Now the most surprising thing is this, that raziya and my father offer namaz regularly, adhere to the orders of islam properly, and offer niaz of Gous-e-azam (Hazrat Abdul kadar jilani) and Kunde ki Niyaz(Imam Jafar-e-Sadiq). but along with these things they say that krishna is part of islam.

I know that this things are of KAAFIRS, and no way krishna is related to islam. and when i started doubting all these things, one day that Angel(baba huzur) left a letter in the niyaz musalla that, Mansoor(my name) is no more in islam, bcos he didnt believe in what Amanullah(my father) and raziya(fathers sister) is telling him, so allah has set him out of his beloved worshippers and allah hates mansoor.

One more thing my father and raziya and other peoples of my family who believed in these things used to keep a letter of their problem in the niyaz they offer, and after 10 or 15 minutes when we all goes to that niaz room, they get answers for their problems written on the same paper in urdu, after having a doubt when i investigated all these things with a proper aalims, those aalims told that nothing is like that, these all r false things, main culprit is Raziya, she has done some amaliyat on my father for his money and wealth. and raziya is writing those letter and telling us that angel has written the answers with order of allah.

also aalims told that water of these peoples house is haram on momin, they r kaafiro mooshrik

after that i advised my father several times that these things r wrong. but he became completely against me and now i am out of my house since 6 yrs, i left my house 6 yrs back and came to my Mamu's house in another city.

now, sir please tell me, am i a sinner, i tried a lot to bring my father on right path but, he believes only and only his sister, no one else not even my mummy.

now i m married to my mamu's daughter since 5 yrs and has a son of 2 yrs, when my wife called my father on phone, he told that mansoor has hurted me and my wife (my mom n dad) thats y god will punish you, all your life. Mansoor is a big sinner.

my father is telling me to apologise in front of each and every person of family that whatever i told about raziya is wrong, and raziya is doing all right things.

tell me what should i do, its a serious problem as it is about parents.

i dnt wanna be a sinner in front of allah at the time of judgement day (Qayamat).
