ISLAM, in general, means surrendering one's whole self to Allah, freeing oneself from polytheism and complete submission to the orders and instructions of Allah.
Submission to Allah is a thing which Allah requires of the whole of humanity as He is its Creator. He has created the whole universe and He alone dominates over it. It is the duty of creatures to their Creator and a requisite of their servility to their Lord.
Islam was the religion of Adam, Noah, Abraham, and other prophets up to Muhammad (peace and blessings of Allah be upon them), for their faith was one and the same, although the applied ethics might be different. The Islamic faith consists of six fundamentals:
1. Belief in Allah.
The first fundamental is the most important of all.
2. Belief in His Angels.
3. Belief in Divine Books.
4. Belief in His Prophets
5. Belief in the Last Day.
6. Belief in the Divine destiny.
