Re: Jafri, explain your words more clearly plz
As in Imam Hussain (as) and Karbala is what has kept Islam alive until this day. Without going into depth of history as you guys say that they embraced Islam, but Yazid's grandfather was the first enemy of Islam. You cannot deny that. Then Muawiya fought against both Hazrat Ali (as) and Imam Hassan (as). You cannot deny that either.
Yazid was only after power whereas Imam Hussain (as) needed to revive the religion. If Karbala never happened, The so called "Islamic leaders" would continue to oppress. Imam Hussain (as) wanted them to know that the Ahl-ul-Bayt would never back down or listen to such oppressors, such as Yazid.
I am POSITIVE you know enough about Yazid, if Yazid had "won" the battle, he would have made the haram into halal and vice versa, destroying the true essence of Islam.
