In very simple terms a Muslim is a follower of Islam. The word "Muslim" means one who submits to the will of God. This is done by declaring that "there is no god except one God and Muhammad is the messenger of God." In a broader sense, anyone who willingly submits to the will of God is a Muslim. Thus, all the prophets preceding the prophet Muhammad are considered Muslims. The Quran specifically mentions Abraham who lived long before Moses and Christ that, "he was not a Jew or a Christian but a Muslim," because, he had submitted to the will of God. Thus there are Muslims who are not submitting at all to the will of God and there are Muslims who are doing their best to live an Islamic life. One cannot judge Islam by looking at those individuals who have a Muslim name but in their actions, they are not living or behaving as Muslims. The extent of being a Muslim can be according to the degree to which one is submitting to the will of God, in his beliefs and his actions.
A Muslim is one who freely and willingly accepts the supreme power of God and strives to organize his life in total accord with the teachings of God. He also works for building social institutions, which reflect the guidance of God. There are no formal induction ceremonies into Islam. To formally become a Muslim, one has to bear witness to the statement of faith ("La Ilaha Il-lal-lah, Muhammadun Rasoolullah") by saying it. To become a true Muslim, one has to confirm the belief in that statement by heart, tongue and actions.
A Muslim's Character and Behaviour
Islam is a true religion because it teaches a person everything including how to act and behave, how to sit and talk and how to care and share. A Muslim is sure of himself both in this world and in the Akhirah (the Hereafter). He/she is always striving towards "falaah" (success, prosperity) and freedom from anxiety and is not troubled with doubts and conflicts. Read More..
