Sawm is fasting. It's the fourth of the Five Pillars of Islam.
Muslims are required to fast during Ramadan, the ninth month of the Islamic calendar.
During the 29/30 days of Ramadan all adult Muslims must give up the following things during the hours of daylight:
- Food or drink of any sort
- Smoking, including passive smoking
- Sexual activity
Muslims who are physically or mentally unwell may be excused some of these, as may those who are under twelve years old, the very old, those who are pregnant, breast-feeding, menstruating, or travelling.
