Every one knows that YAZID bin MAUVIA killed Imam Hussain (A.S) in Karbala Dasert (IRAQ - ARAB) with the
help of approximately one lack forces.
Shia Muslims are all around the world. Some are ARAB-un-NASAL, some IRANIAN-un-NASAL or RAJPOOT or MALAK or Mangolians or Others may be by birth cristian or Hindu ,sikhs, Budha etc.
Some became shia in North or South America, some in africa, some in Russia Eourop etc. How can we say that they have killed.
Don't we know that i will not be responsible for my forfathers sins.
Dont we know that yazid was from Banu-Omaea not from Banu-Hashims and Dont we know the fact that
85% to 90% Syeds are Shia Muslims all over the world.
