Fascinating ... an old friend of fine, Moh'd Odeh - who was our host in 1999 at the Jordanian Leonids camp & conference http://www.astro.uni-bonn.de/~dfischer/leo99/story.html - in a looong Arabic TV talk show http://www.youtube.com/watch?v=0QWoX0eqXzc discussing the Ramadan lunar sighting problem. I know only a few words, but "hilal" (crescent) comes up pretty often.
