Yes thats very importent and by doing so you probably are doing more justice to the cause of karbala than anything else
but I disagree that mourning someone is neccesarily a Bidah , how can the Prophet mourn for something that has not happened yet ? And do you seriously think Prophet wud fault you for shedding a few tears a year for a beloved grandson or a major companion ? ....problem is that 12er sect has made this into big bussiness and although i dont doubt the religious fervor /devotion of a great many of them........
explain the bolded part plz if u cud. I am part of an org that has organizd quite a few progs so all nature and I seem to have missed out on sumthing.
btw if u want to talk abt commercialism then Hajj has turned into a business like no other. So has Eid, Eid ul Adha, Milad, Naats-nasheeds etc.
