Fasting is one of the five pillars, or practices, of Muslims. Muslim scholars say it is the best of the five pillars, because only Allah knows if you are truly fasting or not. Muslims fast during Ramadan because in Islamic tradition this is the month that their holy book, the Qur’an, was first revealed to Muhammad. They also fast during Ramadan in order to identify with the poor and underprivileged. Fasting is said to improve a person’s standing before Allah.
