Simply by saying with conviction, “La ilaha illa Allah, Muhammadan rasoolu Allah,” one converts to Islam and becomesa Muslim. This saying means “There is no true god but God(Allah) [1],and Muhammad is the Messenger (Prophet) of God (Allah).”
The first part, “There is no true god but God,” means that none has the right to be worshipped but God (Allah) alone, and that God (Allah) has neither partner nor son.
To be a Muslim, one should also:
Believe that the Holy Qur’an is the literal word of God (Allah), revealed by Him.
Believe that the Day of Judgment (the Day of Resurrection) is true and will come, as God (Allah) promised in the Holy Qur’an.
Accept Islam as his or her religion.
Not worship anything nor anyone except God.
