The Five Pillars of Islam are the framework of a Muslim’s life. They are the belief or testimony of faith, prayer, giving zakat (support of the needy), fasting during the month of Ramadan, and the pilgrimage to Makkah once in a lifetime for those who are able.
The testimony of faith is saying with conviction, “La Ilaha Illallah, Muhammadur Rasool Allah.” This saying means “There is no true God but Allah, and Muhammad (PBUH) is the Messenger (Prophet) of Allah.” The first part, “There is no true God but Allah,” means that none has the right to be worshipped but Allah alone, and that Allah has neither partner nor son.
