Wait, did I accidentally cause a sin by swapping sandwiches with my Muslim colleague?

Hey folks, I need some advice. I'm Jewish (atheist) and my friend at work is Muslim. So our office bought us lunch the other day and got a bunch of sandwiches. Some were turkey and some were ham. Our boss, who can be a bit of a jerk, basically said everyone had to take what they got. My friend was really worried because if she got a ham sandwich, she couldn't eat it. I told her that if I ended up with turkey and she got ham, I'd swap with her. And that's exactly what happened, so we traded. Later, another colleague heard about the swap and said that in Islam, it's not right to benefit from giving pork to someone else, even if that person also shouldn't eat it (since I don't keep kosher at all). This colleague isn't Muslim, but now I'm wondering if there's any truth to it? Just to be clear, I'm pretty sure the turkey sandwiches weren't halal-certified either, but my friend generally only avoids pork, she doesn't follow strict halal rules otherwise.
