Ramadan is a holy month of fasting, introspection and prayer for Muslims, the followers of Islam. Fasting is one of the five fundamental principles of Islam. Each day during Ramadan, Muslims do not eat or drink from sunrise to sunset. They are also supposed to avoid impure thoughts and bad behavior. Muslims break their daily fasts by sharing meals with family and friends, and the end of Ramadan is celebrated with a three-day festival known as Eid al-Fitr, one of Islam’s major holidays.
