With all due respect,
First of all, No murder is allowed in Islam. Its absolutely haram to kill. So, if this guy did this act, he himself is to be blamed. DO NOT BLAME ISLAM.
Its the short comming of this ONE guy alone, for whatever reason he did it, Allah knows best, and then this guy.
Blaming all the problems on the Imams and lumping them all together with this guy's acts is utterly unfair.
BTW, Its too early to go on any rants here. The news is still fresh. Why did this Guy chose her. Maybe she ran a Prostitution Ring, for all we care.... who knows...
But like I said, its too early. Even if she did something EVIL, HE SHOULD NOT HAVE KILLED HER. IT IS ABSOLUTELY FORBIDDEN TO KILL INNOCENT in ISLAM. But if the Court system in Pakistan had found that she was guilty of some sort, then the court should have handled her punishment, and Death Penalty is still practiced all over the World, including in USA, they could have hanged HER, but it should have been done by the Court and NOT HIM.
At the end, Please don't say that you are ASHAMED of being a Muslim, that means you are fed-up with Islam... Nowz-Billah.
Islam is a gift from Allah, and we should be thankful for it. If we Do Not understand Islam, and are ashamed of it, then ISLAM is not to be blamed, but we ourselves are to be Blamed for failing personally and not doing any research and discovering the true essence of Islam.
Islam is neither too complicated nor is it to be mocked and taken for redicule. Its a comprehesive and beautiful religion which most Muslim Do not Understand, unfortunately.
When Muslims truly practiced Islam, they were at the Pinnacle of all the facets of civilzed Life. Now, its us Muslims that are Failing as individuals, and Not ISLAM..
Please make that point clear...
