Islam's five pillars define core required practices for Muslims. [definitional]
Five central responsibilities are required of each Muslim. These "five pillars" include five daily prayers, abstinence from food or drink during the holy month of Ramadan, pilgrimage to the holy sites in Mecca, almsgiving to the poor, and the declaration that there is "only one God, and the Prophet Mohammed is his messenger."
DEFINE: Clearly defines the five pillars of Islam and their constituent practices.
