I am a born Muslim living in Canada. Six months from now, me and my 3 siblings are about to get married. My father claims that the marriage will be 'Islamic' but wants to spend thousands on dresses of many of his relatives. He wants a stage, mix gathering, 'barats' packed with people, etc.
If do not take part in the event organized by my parents due to their extravagant ideas, will I be committing a sin?
I want to know what are my Islamic rights as an individual who's going to get married?
Can I completely boycott such an event and do a simple ceremony of my own?
