The Paris attackers hijacked Islam but there is no war between Islam and the west | Tariq Ramadan | Comment is free | The Guardian

the attackers said things that cannot be allowed to go unchallenged. They said they were avenging the prophet. That was wrong. In fact, it is the message of Islam, our principles and values, that have been betrayed and tainted. They refer to Islam to justify what they did. From a religious viewpoint, I feel it is my responsibility to say that this has nothing to do with the message of our religion. I would expect anyone, if something was happening in the name of their country or in the name of their religion, to take a stand. As a Muslim scholar I have to take that stand.
