Mr Rafiq said that the Salafi version of Islam excommunicates Muslims who are not the same as them and under Sharia law, this means that these people can be killed. The Muslim leader, Khalid Rashad, hired a hit man to shoot dead Abdul Hadi Arwani because of a mosque power struggle. Rashad, who was jailed yesterday, decided to carry out the murder following a struggle over who had the right to run the An Noor cultural centre, a mosque in west London.

In a comment piece in The Times, Mr Rafiq said: "The murder of Abdul Hadi Arwani was ordered because of a mosque power struggle. "But we should not lose sight of another factor: the different interpretations within Sunni Islam. "We often hear of the Sunni/ Shia schism, but we should not lose sight of the fascistic purging and intimidation of Muslims within their own branch of the religion."
