Ashurra, is celebrated by Sunni Muslims (Qatar is mostly Sunni, although there are a number of Shiite expats living and working here) as the day Noah's ark found ground, the day Abraham was born and the day the Kabaah*, the holiest place in Islam, was built.
Qatar's currency (QAR or QR) is the riyal. The riyal is found in denominations of 1, 10, 50, 100 and 500 notes.
Coffee is extremely important in Qatari culture. Arabian coffee is of a very high quality and made from a lightly roasted bean spiced with cardamom and either sweetened or served with dates. It is drunk in small, thimble-like cups in homes and offices.
