Hmm, according to [url=http://pubcouncil.kuniv.edu.kw/ajh/home.aspx?id=8&Root=yes&authid=1697]this source[/url] the city of Al-Jabiya was only 80 km south of Damascus.

Much further into the Levant than I expected. But it makes sense when I look at the map of current Rashidun holdings. Anyway, currently working on that post :)

Also, looked up the month of Mihr, and apparently that falls during September/October on the Gregorian calendar, meaning RP time, if we follow that date, would be rather late in 634 AD.

I was thinking it would be nearer April 634 AD (was actually going to go for 18th April), as the Muslim conquest of the Levant began around that time
