Of the Five Pillars of Islam, the fast is the most well known.

Every day during the month of Ramadan, muslims fast from dawn to dusk. They abstain from food, drink, and sex.

Those who are unable to fast during Ramadan, such as the sick or pregnant, can make up the fast for an equal number of days anytime during the year.

People who cannot fast at any time must feed a needy person for every day of fasting they miss.
