As a Christian, I'm into loving my neighbor, but I only have one muslim friend and I'm cheap, so he'll probably get nothing. Maybe an apple cake.
Perhaps a pork pie or better a copy of the Bible. This person may hate you for this, but in the after life, he will not be able to refute your attempt to bring him to Jesus. And, perhaps the Bible will bring him to Christ. After all, how much does a bible cost compared to entreaty?
