If you want to be accurate, you will probably have to use either Saladin or something from the time of Mohammed himself.
(Like any other religion, current day Islam has a lot of... propaganda mixed in, unfortunately in the form of Fatvas. Fatva is basically a learned scholar of Islam answering a generationally new problem that isn't written in Qran like "is it ok to use dsl connection supplied by a heathen company? ". Saladin and Mohammed eras are probably the only eras (and people / organisations) where you can find decent and unbiased info on)
