As salamualaikum,I've been married past 2months. My problem is,I did nikaah without my parents permission and I'm major.

Nikah - Wikipedia, the free encyclopedia

Marriage in Islam: Nikah

My understanding of your question is that you are unsure of how to tell your parents about your marriage, and are in fear of what they will do.

I think this is something you, and your husband must do together, after consulting with an official of your faith.

It is unclear if you are of Hindi, or Muslim faith from your question.
