Almost from the moment he sits down, Shaykh Muhammad Hisham Kabbani goes on a sustained frontal attack on Wahhabism, the strain of Islamic thought that is currently and widely believed to be the ideological well-spring of Islamic extremism.
If Wahhabism had been an object standing right before him, it would have been reduced to pulp by the end of the hour-long interview.
But Shaykh Kabbani will tell you that it is not because he hates the Wahhabis. The chairman of the Islamic Supreme Council of America, a religious organisation based in Washington DC whose mission, among others, is to 'educate government officials on the religion, culture and history of the Muslim world', says he is worried because Wahhabism is like an an octopus.
'Its tentacles are reaching everywhere.'
