The Five Pillars of Islam
The Testimony of Faith (Shahadah) - the declaration that there is none worthy of worship except Allah (Arabic for God) and that Muhammad is his messenger.
Ritual Prayer (Salat) - establishing of the five daily Prayers.
Obligatory (religious) almsgiving (Zakat) - which is generally 2.5% of the total savings for a rich man working in trade or industry, and 10% or 20% of the annual produce for agriculturists. This money or produce is distributed among the poor.
