According to the Holy Quran.......
One may eat and drink at any time during the night "until you can plainly distinguish a white thread from a black thread by the daylight: then keep the fast until night".
The good that is acquired through the fast can be destroyed by five things The telling of a lie.
- Slander
- Denouncing someone behind his back
- A false oath
- Greed or covetousness These are considered offensive at all times, but are most offensive during the Fast of Ramadan.
During Ramadan, it is common for Muslims to go to the Masjid (Mosque) and spend several hours praying and studying the Quran. In addition to the five daily prayers, during Ramadan Muslims recite a special prayer called the Taraweeh prayer (Night Prayer). The length of this prayer is usually 2-3 times as long as the daily prayers. Some Muslims spend the entire night in prayer.
On the evening of the either the 21st, 23rd, 25th, 27th or 29th day* of the month, Muslims celebrate the Laylat-al-Qadr (the Night of Power). It is believed that on this night Muhammad first received the revelation of the Holy Quran. And according to the Quran, this is when God determines the course of the world for the following year.
When the fast ends (the first day of the month of Shawwal) it is celebrated for three days in a holiday called Id-al-Fitr (the Feast of Fast Breaking). Gifts are exchanged. Friends and family gather to pray in congregation and for large meals. In some cities fairs are held to celebrate the end of the Fast of Ramadan.
