The teachings of Islam are comprised of both faith and duty (din). One branch of Muslim learning, "Tawhid", defines all that a man should believe, while the other branch, "Shari'a," prescribes everything that he should do. There is no priesthood and no sacraments. Except among the Sufis, Muslims receive instruction only from those who consider themselves adequately learned in theology or law.
The five pillars of faith are observances in Islam which are duties each Muslim must perform.

1. Creed (Kalima)- One must state, "There is no God but Allah, and Muhammad is the Prophet of Allah." publicly to become a Muslim.

2. Prayer (Salat)- Prayer must be done five times a day (upon rising, at noon, in mid-afternoon, after sunset, and before going to sleep) towards the direction of Mecca. The call to prayer is sounded by the muezzin (Muslim crier) from a tower (minaret) within the mosque.

3. Almsgiving (Zakat)- Muslims are legally required to give one-fortieth of their income to the needy. Since those whom alms are given are helping the giver achieve salvation, there is no sense of shame in receiving charity.

4. Fasting (Ramadan)- During the holy month of Ramadan, faithful Muslims fast from sunup to sundown each day. This develops self-control, devotion to God, and identity with the needy.

5. Pilgrimage (Hajj)- Each Muslim is expected to make the pilgrimage to Mecca at least once in their lifetime if they have the means to do it and are physically capable of the trip. It is an essential part of gaining salvation, so the old or infirm may send someone in their place. It involves a set of rituals and ceremonies.
