We're going in absolute circles here. The question has been repeatedly asked and repeatedly answered. This thread ain't going anywhere like the previous one.
No circles, no answer.
You guys aren't giving answers, we ask "How was Islam saved by this rebellion?"
You guys reply "Husayn stood up against the tyranny of Yazid."
Great, we all know he stood up and rebelled, HOW DID IT SAVE ISLAM!?
Were people over-joyed by Yazid's leadership for example? No they weren't, people actually criticized Mu`awiyah for appointing Yazid and this was before Husayn's rebellion. A ton of other personalities had issues with Yazid being in this position before this rebellion.
Have people become more religious after this rebellion? No evidence suggests this. Were people following certain practices, then they changed their Fiqhi views after the rebellion? No evidence of any of it.
Like I said I don't want to keep repeating myself. Take a look at the thread Farid closed down. It's all there, unless you want me to repeat it again.
The sixth Khalifa of the Muslims, Yazeed ibne Moawiya, wanted Hussein to give allegiance to him. Hussein refused and I told you why.
Refer to the previous thread why Hussein's allegiance was so important for Yazeed and why it was so important for Hussein to refuse.
You and some others consider this as a very horrible and terrible tragedy. It was mass murder or I don't know how you see it. But the fact is that this tragedy wasn't committed by Yazeed, oh no. It was actually committed by the sixth reigning Khalifa of the Muslims. It was committed by the Muslim army on the orders of the Muslim government. Basically on the orders of your Khilafat which you so rightly believe in.
Moawiya chose and appointed his own successor and because he (Yazeed) turned out to be a bad dude you probably would reject the concept of consultation (Shura) here, although Moawiya was advised by his administration (close advisors) and people accepted Yazeed. Otherwise you would see a rebellion if not a revolution. Only some opposed.
Where as Abu Bakr did exactly the same thing what Moawiya did and that is chose and appointed his successor (Omar). And since Omar was a good dude, compared to Yazeed) and a close companion and relative of the Prophet (s) you bring in consultation (Shura) here and turn a blind eye to the matter.
So what exactly is Consultation (shura) and what are the circumstances and conditions concerning it? How is shura conducted? Surely it must have a method a procedure. All these things/issues are extremely important and connected to each other, one way or another. We need to discuss them but with an open mind to understand and to get to know the other.
