How to prove this to someone who thinks otherwise?
Re: “ISIS has nothing to do with Islam”.
They have everything to do with it. They think you perhaps are not following the right version if Islam. Thus the push for wiping political Islam in all forms.
Re: “ISIS has nothing to do with Islam”.
I think it is very difficult to explain this premise as all the recruits of ISIS are Muslim 
Re: “ISIS has nothing to do with Islam”.
So I’ve learnt we can’t keep shouting the slogan…we need to take some blame for it?
Re: “ISIS has nothing to do with Islam”.
Your statement is not factual so you cannot prove it. ISIS might say that you are not a true Muslim. Who is to judge whose version of Islam is correct ?
Re: “ISIS has nothing to do with Islam”.
ISIS is like the crusaders, isn’t it? You can tell they’re in it for power and money. I mean for a sound mind it’s not too difficult to see the difference between a common Muslim and an ISIS recruit.
What I want to know is this…what is the role that Islam has played in creating this monster?
Re: “ISIS has nothing to do with Islam”.
send them links of your fav Chris Hedges… or Noam Chomsky.
Re: “ISIS has nothing to do with Islam”.
When the average Islamic State (ISIS) member is asked why he is fighting, he typically responds, “So that Sharia prevails and Islam’s banner stays high.”
Who Holds the Real Power in ISIS? - US News
Despite the debate over whether ISIS represents Islam and what “true Islam” is, Islamic movements, sects and scholars perceive IS as truly believing it is enforcing the rule of Allah according to the Quran and the Hadith under the guidance of the organization’s Sharia Council, probably the group’s most vital body. The council’s responsibilities include overseeing the speeches of the self-declared Caliph Ibrahim (Abu Bakr al-Baghdadi) and those under him, dictating punishments, preaching, mediating, monitoring the group’s media, ideologically training new recruits and advising the caliph on how to deal with hostages when it is decided to execute them.
Re: “ISIS has nothing to do with Islam”.
The only valid argument I have is that majority of Muslims condemn ISIS and this should be enough proof ISIS being an unIslamic group. Just like in case of khwarij.
Re: “ISIS has nothing to do with Islam”.
Do a majority of Muslims condemn other forms of terrorism carried out by Muslims in the name of Islam or do they try to find justification for who created them, the big bad USA, Israel, conspiracy of the west etc ? Examples are Al Qaeda, Taliban, Hezbollah, Palestinian terrorism, LeT, LeJ and the list goes on.
The problem is that once you try to justify any one of these groups, you lose the moral ground to condemn ISIS since is just a few degrees more extreme in terms of its methods and the cause that it stands for.
Re: “ISIS has nothing to do with Islam”.
Whoever created them is a different debate. Majority of Muslims do condemn other terrorist groups you named.

You are right that is what the average ISIS member will say … And you are right it is hard to base whose version of Islam is true on say so … The only true versions that should be considered orthodox and true are those that are supported by scholars who have the license to deem a given activity allowed or impermissible … A good intention alone cannot be the means to ascertain truth of authenticity of a faith system … What needs to be established is which understandings are taking in to account the widest traditions and fuller context.
What is problematic in your argument is that you are asking to not only entertain a gross minority i.e. Less than 0.01% of the Muslims as legitimate but also asking us to place the common average ISIS member’s sincerity as a qualifier for the truth of the faith over the true license given to the scholars of the Muslim world by their teachers.
Re: “ISIS has nothing to do with Islam”.
everytime a terrorist attacks takes place billions of muslims are suppose to condemn it. Looking at your own post did the big bad USA condemn Israeli terrorism in gaza last year. Just a straight yes or no will suffice.
Re: “ISIS has nothing to do with Islam”.
Muslims scholars’ open letter to ISIS: Baghdadi, caliphate’s actions against Qur’an, Islam.

This talk was given by an aalim on the topic:
Re: “ISIS has nothing to do with Islam”.
Somehow they seem to be related for a lot of Muslims I have spoken with, both face to face and on this forum. The moment you caveat a condemnation with "ISIS is bad butUS involvement in Iraq is responsible for creating it, you are deflecting the blame from ISIS to US. The condemnation has to be unequivocal to be sincere.
The caliph of ISIS Abu Bakr Baghdadi has a BA, MA, and PhD in Islamic studies and was a mosque cleric. All sound qualifications for his interpretation of Islam to be deemed authentic, wouldnt you say ? Why then would a non-Muslim lay person not believe that what ISIS is doing is Islamic ?
Re: “ISIS has nothing to do with Islam”.
but I will respond nevertheless. There are US leaders who have condemned Israel. However, your example is flawed since Isarel’s actions were not due to the US. Israel is a sovereign country, and took whatever actions it deemed necessary to protect itself and send a message to the Palestinians. You may disagree with their actions, but they did not do it in the name of USA.
As to your other question, the OP had asked how Muslims can prove that ISIS = Islam hence the discussion. You don’t want to condemn ISIS or terrorism, thats your choice.
Re: “ISIS has nothing to do with Islam”.
sorry but this is the dumbest thing I’ve read in this thread…may I ask who is the genius who made this rule to detect sincerity of Muslims?
Re: “ISIS has nothing to do with Islam”.
How do you know I dont want to condemn them or what actions I have taken in my life against these people. Do you know? If not than stop this nonsense. As for Israeli terrorism every time they carry out a massacre instead of condemning their brutal actions the US congress votes for more armaments to them. But than you would not condemn that. Would you? Russian action in Ukraine are met with sanctions, Israel terrorism is rewarded with more armaments. ISIS are the scums of the earth but then so are many others one close to the ISIS supported by your beloved USA. Since the explosion of Islamophobia the Indians have been riding on the tailcoats of the West to spew their hatred as well.
You still did not answer my question, but than I didnt expect you to.
Re: “ISIS has nothing to do with Islam”.
See this is the attitude of a bigot. If you had the sincere intention you wouldn’t have accused ehsan bhai of not condemning ISIS or terrorism. Please do us a favour and not post in this thread…I don’t need your “sincere” advice.
