Happy New Year (again) and Yet Another Calendar Question!

So January 25th was Tu B'Shvat, the Jewish New Year for Trees
(what an odd name that is.  It's like calling US Independence Day
 the "Iv of July").

Yesterday was the first day of the Chinese New Year (Wooden Rooster,
yǐ-yǒu, Huángdì 4703).

And today is the first day of the Muslim new year (Anno Hegirae 1426).

Which brings up my next OT calendar question: how do you spell the
Arabic month names?  The Romanizations seem to be all over the place.
I have the Romanizations from the Calendrical Calculations book (sadly,
not the Arabic version, even though it was also included with the book -
the book is packed in a box somewhere), which tells me that the current
month is <Raby`al-awal>.  Is there enough information there for a
lossless mapping aback to the Arabic?  What is that, Reh, Beh, Hamzaa,
Lam, Waw, Lam?

Any help appreciated.
