What the Shi’ah do on ‘Ashoora’ is bid’ah (innovation) and misguidance


I am living in dubai and here huge number of shia are pesent arround us they always say that doing maatum on 9 and 10 muhaaram is right and this is the proof that we love hazrat husain and hazrat yaqoob also said “Hazrat Yaqoob (a.s.) cried and said a word (Hey Yousuf) he cried that in result of he became blind and thier rest sons who were wrong asked him if you cried like this than you will hurt yourself and no dought you will die one day while crying. THEN Haszar Yaqoob (a.s.) replied I cried and tell all my tregedy to ALMIGHTY ALLAH and I know something from GOD” please tell me the answer as soon as possible that beating chest is right or wrong?
