The chief executive of the Quiliam Foundation, Haras Rafiq, has claimed that civil war has spread onto the UK's streets.
He said this the killers deemed their victims "not being Muslim enough" and it has led to "ISIS-style" killings on British street.
He said: "The last three killings of Muslims to be picked up by the media have been carried out by those who have decided that their victims 'are not Muslim enough'."
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.
