He, peace is upon him, would lead the Muslims in submission to: The Rabb, The Lord, The Elah, The God, Allaha in Aramaic, Allah in Arabic. Allah is the only Arabic name in existence that is gender less.
My Jesus or God, would think the same about Muslims as he would Catholics, Jews, as long as they were good person. I believe most religions basic rules are to be kind, patient, in some way forgive tress passes, or treat others as you would want them to treat you, fairly. Most people of all religions I think are good, but some are not. And they make fools out of the ones who do. Every group of people, by religion, race, nationality, political view, and station in life has some people who take advantage of other if they can. I would think Jesus would not approve of them. As I said the core of be a good person are in all religions, some of the rules, to honor Jesus or God, seemed normal by society of their time. Rules made mostly by rich men, who wanted to keep their class, to stay superior, or in charge of others. If any religion and its faith, helps you to be a good person, better person, and gives you comfort, that is where it should end. As we do not want others to make fun or dismiss our faith you or we should not dismiss or make fun other other faiths.
