@adrenalina I did ask my FI what the concern is with being "bound" and he just assumed that Muslims aren't allowed to be bound by another religion. He didn't want to ask the follow-up question. I think where we are right now is a Christian ceremony though his Imam says this is not permissible. He really trusts this Imam's opinion as he was close to his late father and he's reluctant to stray far away from his advice. So the ceremony will be Christian and we're signing a Muslim marriage contract. All of this is much more complicated than either of us imagined.
