The Muslim Holy month of Ramadhan which started this week worldwide is the most sacred month of the year for Muslims and it is believed it was during this month that God revealed the first verses of the Quran.
During the entire month of Ramadhan, Muslims fast every day from sunrise to sunset.
It is meant to be a time of spiritual discipline where a Muslim faithful deep contemplates of one's relationship with God, extra prayer, increased charity and generosity, and intense study of the Quran.
During Ramadhan, Muslims wake up well before dawn to eat the first meal of the day, which has to last until sunset.
At the end of Ramadhan there is a big three-day celebration called Eid al-Fitr, or "the Festival of the Breaking of the Fast."
It's kind of like the Muslim version of Christmas, in the sense that it's a religious holiday where everyone comes together for big meals with family and friends, exchanges presents, and generally has a lovely time.
At dawn, they perform the Morning Prayer. Muslims are not supposed to avoid work or school or any other normal duties during the day but instead some work for fewer hours.
