New Muslims / Non Muslims
On the authority of Abu Abd al-Rahman ‘Abdullah bin Umar bin al-Khattab (radiyallahu anhuma) who said: I heard the Messenger of Allah (sallallahu ‘alaiyhi wassallam) say: “Islam has been built upon five things – on testifying that there is no deity worthy of being worshipped save Allah, and that Muhammad is His Messenger; on performing salaat (ritual prayer); on giving the zakat; on Hajj to the House; and on fasting during Ramadan.”
