I am very disappointed with some of the comments that have been made on here saying that so and so is a qadyani, who are we to judge anyone.
Can we guarantee ourselfs of dying with the kalimah, how many commandments of Allah do we break, how many sunnah of Muhammed (saw) do we have inside us so why are we throwing dirt on someone else when we aren't perfect ourselfs, we need to give a long hard look at ourselfs before we start to judge other people.
This Brother has asked us a question and mashallah some people have gave him good advice, it is our duty as muslims to help him as much as we can so he can help his parents stay on islam and if we dont help him by throwing dirt at other people not only will he not be able to help his parents we as muslims will be held resonsible about this by Allah on the day of judgement, what answer will we give to Allah, also next time this brother or anyone else will think 100 times before he asks a question because he knows he may not get the help he is looking for.
Brother you should contact a scholar immediately and take him to your house because you dont want the local public too gossip about it, that way what ever he says to you and your parents will stay behinds close doors and inshallah you will benefit with the advice he gives to you.
Brother you did the right things by asking for help also make dua to Allah that he guides your parents on to the right path an we should make dua as well that Allah guides this brother's parents also our parents and the whole ummah on the right path. ameen.
I am no scholar I only said what my heart told me to say and what ever my heart said was put there by Allah.
