firstly sufism isn't extreme or radical. your husband just wants to be more God conscious and that is his personal decision
he is not insisting that you do things differently, he wants to change himself. as long as it is not affecting how much he contributes in terms of parenting/household stuff. I don't really see the issue. unless I have read it wrong and he is changing how you lead your life?
also I am confused as music is integral to sufism, so why would he stop listening to music?
what he chooses to wear, if he doesn't want to go to the beach, if he doesn't consent to certain sexual activities - that is up to him. he is a human being, he is allowed to change his viewpoint with time, as are you. why are you being so controlling? if he wants to spend an hour at night praying, what's your problem? if he was spending an hour at night watching TV, and posted this thread, you would be told you were being controlling. but because you are the woman and your husband is a religous Muslim man, you are getting these responses.
if any woman had posted that they no longer wanted to do x y z sexual activity for whatever reason, the support would be universal. he doesn't owe you sex of any kind.
the bottom line is however that if you feel your beliefs and values no longer align, then you should re evaluate your relationship. maybe go for counselling?
also you could consider moving this to the Muslim mumsnetters board as a lot of the responses you will get here will not be based on any understanding of islam/sufism.
