After Imam Hussain Shahadat, the atrocities that were committed on Ahlul Bayt, why do we forget them and start to celebrate from 12th? I belong to a sub sect of the Shia community and in my community, from the 12th there are mass weddings and other celebrations also. I feel this is wrong. But I don’t have enough knowledge to make my point. Can someone please guide me with points I can make to make people understand that 11 and 12 is as important as Ashura.
