The definition of the Muslim is; one who follows Islam and the teachings of Islam is a Muslim.
And we believe on what Islam teaches us.
Islam is derived from the Arabic root "Salema": peace, purity, submission and obedience. In the religious sense, Islam means submission to the will of God and obedience to His law.
The Doctrine of Islam
Muslims summarize their doctrine in six articles of faith:
1. Belief in one God (Allah), Who cannot be seen by us, there is no image or idol of Him. Muslims believe Allah is one, eternal, creator, and sovereign.
2. Belief in the angels
3. Belief in the prophets: The prophets include the biblical prophets but end with Muhammad as Allah’s final prophet.
4. Belief in the revelations of Allah: Muslims accept certain portions of the Bible, such as the Torah and the Gospels. They believe the Qur'an is the preexistent, perfect word of Allah.
5. Belief in the last day of judgment and the hereafter: Everyone will be resurrected for judgment into either paradise or hell.
6. Belief in predestination: Muslims believe Allah has decreed everything that will happen. Muslims testify to Allah’s sovereignty with their frequent phrase, inshallah, meaning, “if God wills.”
The Five Pillars of Islam
These five tenets compose the framework of obedience for Muslims:
1. The testimony of faith (shahada): “la ilaha illa allah. Muhammad rasul Allah.” This means, “There is no deity but Allah. Muhammad is the messenger of Allah.” A person can convert to Islam by stating this creed. The shahada shows that a Muslim believes in Allah alone as deity and believes that Muhammad reveals Allah.
2. Prayer (salat): Five ritual prayers must be performed every day.
3. Giving (zakat): This almsgiving is a certain percentage given once a year.
4. Fasting (sawm): Muslims fast during Ramadan in the ninth month of the Islamic calendar. They must not eat or drink from dawn until sunset.
5. Pilgrimage (hajj): If physically and financially possible, a Muslim must make the pilgrimage to Mecca in Saudi Arabia at least once. The hajj is performed in the twelfth month of the Islamic calendar.
