In essence, what your question is asking is 'If I threaten someone with something I know to be abhorant to them in order to extract information, would it work?' And the answer is, yes, possibly; but it's what we call "torture"!
According to the Koran, terrorism is forbidden by Allah, ergo anyone committing a terrorist act in the name of Allah has broken God's law. Of course, I supect you're talking about terrorists from Islamic states, which is a subtle difference, and they might well believe that their transgressions might be forgiven. Dogma, eh?
