Re: religion vs rasms
As I said it is cultural related so one who do, its all related to him/her i.e. wordly matters or affairs. Islam tells what is right and wrong and what is permissible and not permissible. Bringing something from a religion and apply it as permissible not permissible or right and wrong in shaadi and than declaring this or that rasms is permissible or not permissible, right/wrong nothing have to do with Islam.
If we follow our religion than there will be no questions/clarification whether such and such rasm is permissible (right) or not permissible (wrong).
