The world's more than 1.5 billion followers of Islam have begun celebrating the holy month of Ramadan. The faithful, from Jerusalem, to Indonesia and nearly every part of the globe, perform traditions including the extra lengthy "tarawih&quot); prayer, in observance. In the Islamic tradition, Laylatal-Qadr, or the 'Night of Power,' will be observed during one of the last ten nights of Islam's most holy month.
