Islam/Judaism/Christianity Venn diagram -- assistance needed

MrWhatsit is working on a Venn diagram that displays Judaism, Christianity, and Islam. So what he needs is to be able to include commonalities between each pair of religions that are not shared by the third. For instance, the Judaism-and-Islam-but-not-Christianity portion of the diagram could include, “Does not eat pork”; “men cover hair when praying”, and so forth.

He’s having some trouble with the Christianity-and-Islam-but-not-Judaism section; does anyone have any suggestions? Feel free to throw out suggestions for the other parts of the diagram as well.

And, before anyone asks, he’s working on it as a learning aid for the junior high kids he’s teaching right now.
