The word Ramadan is derived from the word ramd "to burn". The entire month is spent fasting from dawn to dusk. The name came from the time before the Islamic calendar, when the month of Ramadan fell in the summer. Fasting during this month is often thought to figuratively burn away all sins. Muslims believe that the Qur'an was sent down to the earth during this month. Furthermore, Muhammad told his followers that the gates of Heaven would be open all the month and the gates of Hell would be closed. The first day of the next month is spent in great celebrations and rejoicings and is observed as the ‘Festival of Breaking Fast’ or `Eid ul-Fitr
