I should have been more specific, it's about praying to a specific place. Jews face the western wall in Jerusalem, Muslims face Mecca. And they do this in or out of the synagogue (or mosque as far as I know). I've seen people get out a compass!
> Christian clerics and devout laypersons pray the Liturgy of the Hours daily.
This might be more analogous, but the "devout laypeople" seems less analogous, as it's got the status of a commandment in Judaism and Islam.
> Finally many Christians observe religious dietary requirements involving fasting and abstinence from meat.
In this Christianity really differs from Judaism and Islam. I'm talking about ritual slaughter and avoiding eating specific animals, not general periods of abstinence from meat.
All in all obviously Judaism and Christianity share a lot too, I'm just suspicious of the claim that they shares more with each other than Islam when my experience is not like that at all.
