Salaamalaikum. I have parents who have had long standing issues with my brothers wife. There had been some past problems that have to this day gone unresolved. It is now my nephews wedding, and my parents do not want to attend as a result of their problems with his mother. They also do not want me or my wife to attend my nephews wedding in fear of people telling us bad things that will drive me away from my parents.
1. What does islam say on their rights on this matter. In light of no valid reason to not go, should I disobey and go to the wedding?
