In Islam, Ramadan is a holy month of fasting, introspection and prayer. Fasting is one of the five fundamental principles of Islam. Each day during Ramadan, followers of Islam, known as 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. The end of Ramadan is celebrated with a three-day festival known as Id al-Fitr that is considered one of Islam’s major holidays.
