Islam is based on five pillars which the Messenger (peace and blessings of Allaah be upon him) has explained for us, when he said: “Islam is built upon five [pillars]: the testimony that there is no god but Allaah and that Muhammad is the Messenger of Allaah; establishing regular prayer (salaah); paying the zakaah; Hajj (pilgrimage) and fasting Ramadaan.” (Agreed upon; narrated by al-Bukhaari, no. 8)
