Excerpt:
Bilal Philips was once a guitar god. Now he is trying to convince Muslims that God doesn't want them listening to guitars.
A Saudi-trained Canadian, Mr. Philips is among a small group of lecturers who preach against most forms of music — a controversial prohibition that surfaced in Manitoba recently, where a dozen Muslim families want to pull their children from music class.
"A heart filled with music will not have room for God's words," he writes in his book Contemporary Issues, which also defends child marriages, wife beating, polygamy and killing apostates while calling homosexuality "evil and dangerous."
