Ok, so you are not a muslim, and as far as I can tell you are a non-believer (as in you don’t believe that the islamic Allah exists¹). Therefore, it puzzles me that you use those typical islamic expressions (Peace be unto Him) that believers use by reflex, more or less indistiguishable from you actually believing that Muhammed was an actual prophet from an actually existing Allah. Can you enlighten me here?
¹ As opposed to “you believe that the islamic Allah does not exist”
