Muslims fast during the month of Ramadan from dawn to sunset. Fasting involves abstaining from food, drink, and intercourse, and encourages resisting temptations. It aims to redirect the heart from worldly activities and cleanse the soul. Muslims who have reached puberty and are physically and mentally fit are expected to fast, unless exempt due to health issues, old age, pregnancy, menstruation, or travel. The month involves increased worship, prayer, charity, and Quran recitation, as well as sharing meals and gifts with family and friends.
