The Spirituality of Islam

The Five Pillars of Islam (arkān-al-Islām أركان الإسلام; also arkān ad-dīn أركان الدين "pillars of religion") are five basic acts in Islam, considered obligatory for all Muslims.
The Qur'an presents them as a framework for worship and a sign of commitment to the faith. They are (1) the shadaha (creed), (2) daily prayers (salat), (3) fasting during Ramadan (sawm), (4) almsgiving (zakat), and (5) the pilgrimage to Mecca (hajj) at least once in a lifetime.
