Egyptian supporters of the Muslim Brotherhood read the Koran, Islam's holy book, outside Cairo's Rabaa al-Adawiya mosque on July 10, 2013 before breaking the fast on the first day of Islam's holy month of Ramadan. Tens of millions across the Muslim world fast from dawn to dusk and strive to be more pious and charitable during the month, which ends with the eid holiday.
