The West does need to understand that while some Islamic scholars, within Saudi Arabia and in the wider world, may seek to follow a path that goes back to a fundamental view of Islam and may wish to lead a more conservative life, they do not accept suicide bombings or the taking of innocent human life. No one can do this and be a true Muslim.
They all agreed that only those trained within the traditional eight schools of Islamic jurisprudence have the authority to issue fatwas. This might seem an academic point, but it is fundamental to undermining the legitimacy of so called Islamist (rather than Islamic) terrorism. This declaration makes clear that none of these supposed fatwas is legitimate or Islamic: Islam has united and declared the terrorists to be in breach of the Islamic faith.
