The Messenger of Allah (PBUH) said, “Islam is built on five [pillars]: bearing witness that there is no god but God and Muhammad is His prophet, establishing the prayer, giving zakat, hajj, and fasting during Ramadan.”

• The Testimony of Faith (Shahadah) - the declaration that there is none worthy of worship except Allah (Arabic:God) and that Muhammad(PBUH)is His last 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.
• Sawm, Fasting
• The Pilgrimage to Mecca (Hajj) - this is done during the month of Zul Hijjah, and is compulsory once in a lifetime for one who has the ability to do it. If the Muslim is in ill health or in debt, he or she is not required to perform Hajj.
  Note that the Shi'a branch Amr Bil Maruf and Nahi Anil Munkar (Enjoining the Good and Forbidding the Evil) is also commanded in Sunni Islam but not at the level of The Five Pillars of Islam
