I do not understand this mindset. Why not instead learn from your own Christian brothers and sisters of various backgrounds who keep to the daily hours of prayer (which are seven in Christianity, not five as in Islam), and the vigils, and the fasts (plural; not just one, as with Muslims), and so forth?
"No peace among the nations
without peace among the religions.
"No peace among the religions
without dialogue between the religions.
"No dialogue between the religions without investigation of the foundation of the religions."
― Father Hans Kün, a Roman Catholic priest and theologian, who present at Vatican II
Also, just from a common sense perspective, the world has 2.1 billion Christians in it and 1.5 billion Muslims in it. If the two groups don't learn to get along and understand each other better, we're in for a rough third millenia here. Nobody is ever going to win that war if it becomes an all out war. Each side would have too many people spread across too many countries to ever secure a decisive win.
Fortunately, the average Muslim, like the average Christian, just wants to have a normal peaceful life. Get up, go to work, find a spouse, raise some children, etc.. More days off would be nice. Better access to health care. A raise. You know, people are people.
And, really, Islam and Christianity aren't that dissimilar. Both feature the same montheistic God who had an important prophet named Abraham- and its the same Abraham! Both hold Jesus in high regard- one religion considers him a prophet, the other as the Son of God. Each has feasts and fasts (Ramadan reminds me of Lent), each has internal divisions (Catholics and Protestants, Sunni and Shia), each has fundamentalists, liberals, and everything in between. Really, when you think about how different religions could hypothetically be, Christianity, Islam, and Judiasm all have a ton in common with each other, relatively speaking. They all have the same roots- they share the same God, many of the same religious figures, some commonalities in their moral codes (and some differences)- and perhaps most importantly, a shared humanity and a shared planet.
If we're all children of Abraham, then we are all brothers and sisters. Same applies to being children of the same God. Heck, just genetically speaking, we're all related. We all came out of Africa and are east of Eden or whatever. Do Muslims have a story about Adam and Eve in Eden in their scriptures or traditions? I wouldn't be surprised if they do.
The better we understand each other, hopefully the less we'll want to fight each other. The alternative to that is scary. Just look at the numbers. Neither group is going away. We need to learn to live in peace.
