Last month, a scholar and critic of Islam, Robert Spencer, was barred entry to the UK, while one of the objects of Spencer's disapproval, Muhamed Al-Arifi, was admitted to Britain with no objection at all from the British government.
Spencer's comments about Islamic extremism were apparently considered too incendiary; Arifi, however, describes the killing of "infidels" as a "great honour" and advocates the murder of Jews. On IQRA TV, he states that:
What was taken by force will be restored only by force, as conveyed by the Prophet Muhammad, who said: "You will fight the Jews." He did not say: You will conduct negotiations, they will make concessions, and then you will make concessions, and then we will reach a compromise and divide Jerusalem... By God, Jerusalem will not be divided. He said in the hadith: "You will fight the Jews and kill them." It was the Prophet Muhammad who said this, not me.
